Pool Flocculent vs Pool Clarifier

It is very easy to confuse the difference between pool flocculent and pool clarifier. As they both deliver a very similar function. However each serves a unique purpose.

A clarifier is a chemical substance that binds the tiniest of debris together to trap it in your filter. The chemicals in a clarifier act like a magnet to the fine debris suspended in your pool to achieve sparkling water.

Pool flocculent works in much the same way, however it is generally used when the pool is so cloudy you can’t see to the bottom the pool. Pool flocculent thickens the particles in suspension and binds them together, so they sink to the floor. Following this you then vacuum the particles to waste.





So when should you use Pool Flocculent or Pool Clarifier?

Pool clarifiers do not work as quickly as flocculents because they are used more for routine maintenance instead of troubleshooting a problem with the pool water.

Flocculents on the other hand work much faster, because it drops the suspended debris to the pool floor before you manually vacuum the debris to waste.

You cannot use flocculent with a cartridge filter unless you have plumbed your system to bypass the filter. Flocculents can create problems with cartridge filter elements if used incorrectly and can reduce the efficiency of your filtration. Similarly, with a media filter you want to avoid trapping the large particles created by the flocculent in your filter as it will affect its efficiency, hence it needs to be vacuumed to waste. When using flocculents because you are vacuuming to waste, your pool water levels drop. This is why you use flocculant as a last resort and should use pool clarifiers as part of your regular pool maintenance routine.

Autumn Pool Care Tips

During Autumn it is important to continue regularly testing your pool water to maintain the required balance. Below are HY-CLOR’s top Autumn pool care tips:

1. Autumn is the season of falling leaves so make sure you regularly clean and remove the leaves from your skimmer box and pool surface. Leaves are one of the main sources of organic material that create phosphates in your pool. Phosphates are a key food source for algae, helping it to grow in your pool. Make sure you regularly apply phosphate remover to your pool to prevent algae blooms.

2. If you have a pool cover, put it to use as it will prevent leaves and debris from becoming trapped in your skimmer. This will reduce maintenance and also help to keep phosphates out of your pool. Remember to remove the cover for a few hours a week to let the pool breath.

3. Autumn is also known for storms and wet weather. Make sure you remove any pool toys from the pool and secure them in a dry location such as a garden shed. Your toys will last longer and it is one less thing you need to worry about keeping clean.

4. Check that all of your equipment is operating efficiently as it has been working hard during the summer season to ensure your pool stayed ‘swim ready’. Check there are no leaks coming from your pump and filter, all of the o’rings are lubricated and there are no visible cracks and that your pool fencing and gate are in working order.

5. As the weather gets cooler at the back end of Autumn, you should reduce your filtrations running time to approx. 4 hours per day. This will take stress off your equipment and reduce your energy costs.

6. With reduced bather loads and the colder weather, your pool chlorine demand decreases. If you have a saltwater pool, you should also consider reducing your chlorine output. Keep in mind the ideal range for free chlorine is between 1-3ppm.

Remember to visit your local Bunnings for your FREE water test or download the HY-CLOR Water Testing App from the Google play or Apple app store.

Rain Recovery Pool Essentials

After heavy rain, your pool needs some TLC to get it back to its sparkling best and prevent it from going green. Below are the ‘go to’ products most pools require. We always encourage a water test to fully gauge your pool requirements, however 90% of the time the three products below are necessary.


All the rain has diluted your pool chemicals and one of the most important ingredients to kill bacteria and germs is a sanitiser. Let’s imagine a glass of cordial is the chlorine in your pool and the concentrated cordial is the ideal chlorine level (active chlorine). Before the rain you had full concentrated cordial, however with all the water that has been added in because of the rain, the strength of the cordial is now a quarter if not less then what it was originally. The same theory can apply to your pool and like cordial you add a little more of the concentrate to get it to the desired level. The most common method to sanitise your pool is liquid chlorine. It is fact acting, instantly raises free chlorine levels and eliminates and controls the bacteria washed in by the rain.

Rain washes in particles that are too small and light to sink to the bottom of the pool. HY-CLOR Super-Floc clumps together these tiny particles so they sink to the bottom of the pools’ surface and can be vacuumed to waste. HY-CLOR Super-Floc is fast acting and will clear the cloudy water.

Phosphate Remover

The rain also washes in organic materials such as soil from your garden, grass clippings, leaves and many other sources. These organic materials produce phosphates that feed algae growth in your pool. To prevent algae growth, we recommend ongoing use of HY-CLOR Phosphate Remover. It will remove the phosphates from the pool and as a result starve algae of it’s main food source, consequently reducing the overall chlorine demand in your pool.

Make sure you visit your local Bunnings to get a free water test using the kiosk or download the HY-CLOR app and test your pool water at home. The results of the test will tell you exactly what is required to balance your pool.

Pool Overflowing From Rain?


With all the rain we’ve had, has your pool water level got to the point where it is now overflowing?

If it has, it’s important that you get and keep your pool level in check as, apart from flooding your backyard and equipment, it can influence your pool water chemistry. The optimum pool water level is roughly in the middle of your skimmer box.




Reducing Your Pool water level

Depending on the type of filter you have there are two ways you can reduce your water level;

1) Media Filter (commonly known as sand filter)
Firstly, make sure the pump is off before adjusting anything to drain your pool water level. On the multiport valve adjust the handle to ‘waste’. Turn the pump on and the excess water will be directed to your waste line. Keep a close eye on your water level as it will not take long for it to reach the desired level.

If you have not backwashed your filter and you have noticed the purity in your water is not same, or that the filter requires more pressure for water to flow through, it may also be the perfect opportunity to backwash your filter. Instead of adjusting your multiport valve to waste, point the handle to ‘backwash’. you will need to backwash your filter until your sight indicator on the side of you filter is clear. Before adjusting the handle on the multiport back to filter you will need to set it to rinse. Rule of thumb is rinse should take about half the time you required to backwash your filter.  Remember each time you need to adjust the multiport valve you need to turn the pump of  first, then turn it back on for each operation.

Once you have decreased your pool water down to the desired level, make sure you turn the pump off and then adjust the multiport valve back to ‘filter’ and continue to run your filtration as per normal.

2. Cartridge Filter (image of a HY-CLOR cartridge filter)

If you have a cartridge filter you can use the drain port, typically found at the bottom of the filter tank. You could also attach a spigot on these ports and then attach a standard garden hose which you can run directly into your waste line.


Pool Water Chemistry

With all the rain that has got into the pool, your pool water chemistry will, more than likely, no longer be in balance. Your active chlorine levels will undoubtedly have been reduced and, if you have a salt chlorinated pool, you may need to add a few bags of salt.

We recommend that you get your pool water tested, either at your local Bunnings or using the HY-CLOR water test app, to ascertain what is required to get the pool back into balance. Your pool may look clear, however, this does not necessarily mean that it is in the correct balance and, untreated, it can quickly turn into a green pool in matter of days. If, unfortunately, your pool has gone green watch our green pool recovery video for advice on how to get it back to its sparkling best.

In many instances, the rain will have washed in organic matter such as soil, dirt, leaves etc. resulting in making your pool cloudy with you no longer being able to see the bottom of the pool. A very good way to rectify this is through the process of ‘shocking and flocking’ the pool.  Shocking the pool with Liquid Chlorine will raise the chlorine level to kill any harmful bacteria and algae washed into the pool as a result of the rain. After waiting 30 minutes you can floc you pool by adding (HY-CLOR Super-Floc). Floccing the pool will target suspended particles, making them heavy and, as a result, drop them to the pools surface. You then need to vacuum these to waste. If your pool water level is overflowing, we recommend you allow approximately 10cm above your desired water line so you can vacuum to waste.

A lot of the above challenges with a cloudy pool, or green pool for that matter, can be prevented by implementing a Preventative Pool Maintenance regime all year round. To learn more about this read our handy tips on ‘prevention is better than cure’.

Prepping for HIGH bather loads

You may have done a pool water test and everything looks ok, but what you may not be aware of is if you are planning on a high bather load over the next coming days it can significantly impact your pool water chemistry.

Each time a swimmer jumps in your pool they are bringing bacteria and germs with them. Body oils, sunscreen, urine and other contaminants all have an influence on your pool water chemistry.

So, what are some of the steps you can take to prep your pool for high bather loads?


1. Test your pool water regularly – using the FREE HY-CLOR water testing app test your pool water before and after higher bather loads to ensure your pool water chemistry is in check. If you need test strips simply drop into your local Bunnings Warehouse and pick up the AQUACHEK 4-in-1 Pool Test Strips 


2. Shock your pool – your pool chlorine demand increases during high bather loads to cope with the bacteria and germs your pool swimmers have brought into your pool water. If your free chlorine is not between 1-5ppm we recommend shocking your pool. The HY-CLOR Super Shock will quickly raise your chlorine levels and eliminate any chloramines that can cause eyes and skin irritations.



3. Preventative Pool Maintenance – Whether it’s the middle of summer or winter we encourage you to follow a preventative pool maintenance regime. This will provide you with the reassurance your pool has the extra ‘insurance’ to keep away algae, phosphates and other nasties. For more information you can read our handy tips blog on ‘Prevention is Better than Cure’.


 4. Check your pool equipment – during swimming season your pool equipment is working overtime to keep up with your pool demands. We recommend you periodically (monthly) check your pool equipment is running efficiently with no unwanted noises, leaks or parts that may need cleaning are addressed. This will not only help maintain a sparkling pool but also ensure you get the longevity out of your pool equipment and keep your costs down.

Prevention is Better than Cure!

With the erratic weather we have experienced this summer it’s harder than usual to keep your pool balanced. Hy-Clor has a range of preventative pool chemicals that help keep your pool in check and ultimately reduce the cost of upkeep.

Hy-Clor Long Life Algaecide

Hy-Clor’s Long Life Algaecide can be used as a preventative algaecide, applied monthly or quarterly. Based on a 50,000 litre pool if you apply 1 litre per month the copper based algaecide will kill and control algae growth. Suitable for all pool types, it can be used in both chlorine and salt chlorinated pools and it’s a great all year round treatment.

Hy-Clor Phosphate Remover

Phosphates are the essential ingredient algae needs to grow. Phosphates are organic materials that naturally occur in your pool, originating from dead leaves, soil, lawn clippings and many other sources. With all the excess rain we have been experiencing a lot of organic matter has been regularly washed into your pool, in turn potentially creating phosphates.

Hy-Clor’s Phosphate Remover targets and removes phosphates from the pool which in turn starves algae of its main food source. The required amount of Hy-Clor Phosphate Remover to be applied will be dependent upon the level of phosphate in your pool. Even if you do not have a phosphate level reading in your pool, we recommend an ongoing monthly dose as a preventative measure.


Hy-Clor Water Clarifier

To make sure your pool maintains that extra sparkle particularly during the summer season a monthly dose of Hy-Clor’s Water Clarifier is recommended. Hy-Clor’s Water Clarifier binds together fine particles that cloud the water, allowing them to be captured by the filter, the result being a clearer, sparkling pool.


Water Test

Last but not least, ensure you are regularly testing your pool water. Using the Hy-Clor app which is free to download online for both Apple and Android phones you can quickly and easily check your pools water chemistry. Alternatively, visit your local Bunnings with a water sample and use the instore kiosk to conduct a FREE water test. The system will deliver your results and provide you with step-by-step instructions on what is required to maintain a sparkling and safe to swim in pool.

How to stay on top of your pool maintenance during a La Nina Summer

Don’t let the wet weather dampen your summer swimming plans. By putting in place a number of preventative measures you can avoid greater cost and reduce the risks of having an unbalanced pool. With the summer season already kicking off with above average rainfall, according to the Bureau of Meteorology it is predicted to continue throughout summer.


Before you treat the pool make sure you stay on top of any leaves, twigs or fallen debris. This should be something you regularly attend to throughout the swimming season.

Water test

We recommend you regularly get your water tested to establish what is required to ensure your pool water is balanced. Use our free water test app available in the app store or google play store, alternatively visit your local Bunnings Warehouse to use our FREE water testing kiosk. It is vital you have the core elements of your pool water chemistry such as Sanitiser (Chlorine or Salt), pH, Total Alkalinity and Calcium Hardness at the correct levels to ensure your pool is at its best.

Preventative Maintenance

Rain washes organic matter, dirt, debris and other elements into the pool that break down into phosphates. Phosphates are what algae feeds on to grow in a similar manner to adding fertiliser and water to grass to keep it healthy and green. As a preventative measure you should add a phosphate remover to your pool weekly. Adding a weekly dosage of 225ml of the Hy-Clor phosphate remover will minimise phosphate levels from being present in your pool.

To also aid in preventing the occurrence of algae, the use of a preventative algaecide is highly recommended. The Hy-Clor long life algaecide is the perfect product for preventative maintenance and will protect a pool from algae for 6 months if used as a preventative product in a 50,000 litre pool.

Chlorine levels

The rain dilutes all the chemicals in your pool water. It’s a bit like concentrated cordial. Once you add it to water its taste is very different. The same theory can be applied to your pool water, however, instead of it being the taste, it’s the water balance that will be affected and the first sign will be the water clarity.

To start with make sure your chlorine levels are within the correct range of 1-3ppm and your pH is between 7.2 and 7.6. If you need to top up your chlorine levels there are a number of chlorine sanitisers you can choose from.

Cloudy Water

If your pool water is cloudy (you cannot see the bottom of the pool) you may need to use a flocculent such as Hy-Clor Supa Floc. This is a high strength flocculent that settles debris and organic matter to the floor so it can be vacuumed to waste.

To ensure your pool maintains its regular sparkle we recommend a monthly dose of a clarifier such as Hy-Clor Clarifier which binds the super fine particles together that the naked eye may not notice. This allows your filtration system to capture what would normally sneak through.

Salt Levels

Last but not least, check your salt levels (if you have a saltwater pool) using our salt test on the water test app or the kiosk at your local Bunnings warehouse. If you have a saltwater chlorinator it will rely on adequate levels of salt to ensure it can produce the correct amount of chlorine for your pool.

How Does Calcium Levels Effect My Pool?

What is Calcium Hardness?

Calcium refers to the measure of the total hardness of which is dissolved minerals such as calcium and sodium. For most pools, the calcium hardness level should be between 200-400ppm and for spas between 150-250. Calcium can also be explained as how ‘soft’ or ‘hard’ the water is. Calcium levels are important to your pool and spa because it provides structural health of the pool itself.

How is it added?

Calcium hardness can easily be raised by added calcium chloride which will come as a flaky, granular form. You can add calcium by dissolving it in a bucket of water and broadcast into the water. When calcium chloride is added to water it will naturally heat up so make sure to keep it away from your skin. Another way to add calcium to your water is to add the required amount into your pool scoop and slowly pull through the water until there is no residue left.

Effects of unbalanced calcium levels?

Low Calcium levels may cause:

  • Leaching of concrete pool surface
  • Damage to tile grout
  • Etching of plaster

High calcium levels may cause:

  • Damage to pool equipment
  • Cloudy water
  • Rough feeling surface
  • Clogged piping

So there you go, now you know what calcium does. If you need extra help, do not hesitate to give us a call on 1800 625 123 for advice on what products are best suited to your pool needs.

Equipment Maintenance

Keeping your pool sparkling clean does not have to be as difficult as you might think. All pools are different and so are their maintenance needs. However, they all share one thing: The secret to perfect pool health is a regular scheduled .

If you choose to handle common problems like leaking pipes or broken pumps on your own, make sure to always consult the manufacturer manuals before fixing or using equipment. No matter if you rely on a service company to take care of your pool, you still need to do a few things on your own to ensure your pool stays in good condition for years.

Check out the tips below to make sure your pool equipment lasts long.

1. Pump Maintenance

The purpose of your pool pump is to suck water from the pool which goes through a filter and is pumped back into the pool. Maintaining a pool pump in prime condition does require year-round servicing, but with these easy steps it will become second nature.

  • Lubricate all union and lid O-rings with a silicon-based lube to make sure they do not dry out, which prevents unwanted air getting into the system.
  • Remove any dust and debris from around the motor to ensure ventilation and free airflow around the pump to cool the motor.
  • Clean the pump basket/filter regularly to avoid debris buildup. If you’re handy with tools you can remove the wet end of the pump to clean out and ensure the impeller is free from debris.
2. Filter Maintenance

The pool filter is crucial for keeping a pool clean and healthy. Whatever kind of filter system you have, it removes larger particles like dirt, hair and insects from the pool water as well as finer particles like bacteria and other contaminants.

Sand Filter:

  • Lubricate all union and neck O-rings with a silicon based lube to make sure they do not dry out.
  • Visually inspect the sand filter for any splits or leaks.
  • Make sure to backwash and rinse once a month to ensure the sand is free to capture any particles.
  • Perform a filter degrease with a filter media cleaner.

Cartridge Filter

  • Lubricate all union and lid O-rings with silicon-based lube to make sure they do not dry out.
  • Visually inspect the cartridge filter tank and lid for any splits or leaks.
  • Make sure to clean out the cartridge element with a high-pressure hose once a month.
  • Perform a cartridge degrease with an element media cleaner.

3. Chlorinator Maintenance

A salt cell also known as a chlorine generator is an important part of every pool. It produces sanitisers that keep your water fresh and clean. However, it requires ongoing maintenance to continue functioning or serious problems can arise.

  • Visually inspect the chlorinator housing for any splits or leaks.
  • Lubricate the cell housing O-ring with a silicon-based lube to prevent it from drying out.
  • Ensure all timers are set correctly and running in time.
  • To remove any calcium deposits, clean the cell and flow sensor with a 15:1 acid solution or a purpose made cell cleaner for no longer than 20 minutes

Smart Chemical Usage

Your pool chemicals can eat up most of your pool’s maintenance cost, but there are a few simple tricks that can help save a lot of money in the long run. Check out our list of helpful tips that could help you save a fortune.

Chemical Balancing

The chemical balance of a swimming pool is vitally important. While it may be extra work to maintain the chemical balance it will help prevent algae and cloudy water from developing. When adding chemicals to the pool there is a particular order they should be added in:

  • After testing the water, if you are required to add pH increaser/decreaser and alkalinity increaser it is best to add the alkalinity increaser on day 1 and pH increaser/decreaser on day 2. If you add them at the same time they will cancel each other out, therefore wasting chemicals.
  • Always ensure your stabiliser level is correct before adding chlorine to the pool. This will ensure that the chlorine is not burnt off by the sun quicker than sanitising the water.
  • When adding stabiliser to the water, make sure to not backwash your filter for at least 3 days. Stabiliser slowly dissolves in the filter, so if you backwash after adding you could be pouring money down the drain.
  • Before adding any chemicals, ensure that your pH is within 7.2–7.6. All chemicals are more effective when the pH is correct.
  • If possible add chlorine or sanitiser’s in at night to prevent unnecessary burning off from UV rays.

Overall, the absolute best way to save money on chemicals is to test the water more regularly. This prevents levels shooting up and down while also creating better quality water and swimming experience.

Solar Pool Cover

Pool covers are a great investment, they have many great advantages in regards to water and chemical savings.

There are three big reasons you need to protect your pool from sunlight.

  1. The first is the bacteria and algae that chlorine has to eliminate; both grow best in warm water with lots of sunlight. So, if they are allowed to grow almost unchecked in a warm sunny pool, you’ll use up your chlorine faster and have to regularly replenish it.
  2. The second is sunlight reduces chlorine’s efficiency. It causes the sanitiser to dissipate faster and the chlorine demand to go up. On a sunny day, it only takes 2 hours to burn off your chlorine by 90%.
  3. Thirdly, to fight evaporation make sure your pool is covered when not in use. A simple solar cover between swims is all that is needed to save precious litres. If you use a pool heater, keep it set as low as possible.

Therefore, unless someone is swimming, cover your pool to save money on water and chemicals.

So, there you have it, once you know how to save money on pool chemicals, it’s not hard to manage efficiency. A lot of it comes down to using tactics so your chemicals don’t have to do as much work.

Chemicals For Autumn

With the summer season now over, you may find that your pool is not being used as much, but that doesn’t mean you should just cover it up and forget about it as the weather is still good enough for a swim every now and then. You want to make sure that you can still use the pool if the need arises. At least, before it all gets too cold.

As the leaves are falling during the autumn season and the temperature begins to drop, it is tempting to just let your pool go to sleep, but that would be a big mistake. There are a couple of pool maintenance tips that you need to implement as soon as possible. Acting immediately will help you save money and more importantly protect your pool from any damages.

Here are some simple things to get started:

1. Clean The Whole Pool

The first thing you want to do is remove all dirt and debris from the pool, this is to ensure you are starting autumn with a clean slate.

  • Thoroughly brush the floors and walls of the pool
  • Scoop and skim all leaves and larger debris out
  • Vacuum to waste any debris that has fallen to the pools floor
  • Clean out all skimmer and pump baskets thoroughly
2. Clean All Filters

This step is very important as over summer a lot of debris and bacteria would have been trapped inside a filter.

  • Sand Filter: Backwash and rinse with a filter cleaning solution. This will breakdown all oil and grease deposits that a regular backwash will not rid of.
  • Cartridge Filter: Remove cartridge from housing and soak in a filter cleaning solution to breakdown all debris deposits, then thoroughly hose down. If your cartridge isn’t cleaning out well, it may be time for a new one.
3. Balance The Pool

Now that the pool is clean and clear, let’s move on to chemicals. As water temperatures get colder, the need for certain chemicals will drop. But it’s still very important to ensure the essential balancing levels are maintained.

  • pH needs to be between 7.2 to 7.6
  • Total Alkalinity needs to be between 100–150ppm
  • Free Chlorine needs to be maintained at 2–3ppm
4. Protect Against Algae

Use an algaecide that is appropriate for your pool. The addition of pool algaecide will enhance and prolong the effectiveness of the chlorine and can act as a valuable backup to the anti-algae effects of regular chlorination.

5. Schedule Regular Shock Treatments

It’s recommended to use a regular shock treatment throughout autumn and winter. Once you’ve added the shock treatment appropriate for your pool–run both the pump and filter for several hours to ensure it has been well distributed throughout the water.

Out of Town Maintenance

So, you’re going away and you’re wondering how to prevent your pool from turning green? Well not to worry, we’ve got you covered!

Here are some best practices for preparing your pool before you head out on that well deserved break.

Going-Away Checklist:
  1. Top up your pool’s water level
    Ensure that the water is at least 3/4 of the way up the skimmer or more. While you’re away, evaporation and water loss will happen, so it’s always best to fill the pool above the normal level to prevent your pump running dry.
  2. Test your water
    Test your pool water to ensure sanitiser levels are stable and pH, alkalinity and stabiliser levels are balanced correctly.
  3. Shock the water
    Once chemical levels are balanced, it’s time to shock the pool. For shocking, there are many types of chlorines that can be used. We recommend using a calcium based chlorine like HY-CLOR Super Shock to not unnecessarily raise your stabiliser levels. For dosage measurements, refer to the product instructions.
  4. Remove debris
    Ensure that the skimmer baskets, filter and pump are clean and free from debris before you leave. If your system has a backwash option, now would be the time to run it, or if you have a cartridge filter, hose down the cartridge.
  5. Keep the pump and filter on while you are away
    Most pump systems have an automatic timer. Set it before you leave to ensure the pool filter system will run at least 4 to 8 hours per day, depending on the size of the pool.
  6. Have a friend or neighbour check on your pool
    For extra peace of mind, have a trusted caretaker keep an eye on the pool. They can check the water levels, the skimmer basket and any problems that may occur.
  7. Put all safety measures in place
    Safety is incredibly important when you are leaving your pool unattended. Make sure you have the proper safeguards in place to prevent an accident. This includes ensuring gate latches are securely locked and remove the solar cover to prevent potential harm to small animals, pets and children.
  8. Winterise your pool
    If you plan to be gone for more than a month, you may want to consider winterising the pool which involves adding a copper based algaecide such as HY-CLOR’s Long Life Algaecide. This extra strength algaecide will work in tandem with the chlorine to prevent algae from blooming.

Prepare For The Long Weekend

With Easter around the corner, it’s time to get the pool ready for the long weekend.

Long weekends are the perfect time to spend some quality time with your family and friends. Not only do you want your swimming pool to be sparkling clear, it also needs to be safe and healthy. Chemical imbalance can cause skin and eye irritations, algae outbreaks and pool surface staining/scaling.

HY-CLOR’s Party Prep chemicals have been designed to provide protection against bacteria and algae whilst maximising the filtration capacity, water clarity and swimmer comfort. We have put together a handy guide to ensure your pool is swim ready

Weekend Prep:
  1. Test and balance waterFirst things first, test your water and ensure that balancing levels are in the correct range.
  2. Remove pool cleaner, hoses and vacuum plateThis is to ensure a full flow of circulation through the skimmer.
  3. Backwash and rinse the filter (backwash 3 minutes and rinse for 30 seconds) or clean out cartridge filterThis is to ensure your filter is free to capture any particles that may be present.
  4. Dissolve the required amount of HY-CLOR Spa Shock (or equivalent non-chlorine based oxidiser) in a clean bucket of water and pour into the pool in batches.Non-Chlorine based oxidisers use active oxygen to destroy contaminants while easing the load of your Free Chlorine Level and preventing the build up of chloramines.
  5. Pour required amount of HY-CLOR Algaecide into the poolThis is used to prevent harmful bacteria and algae from blooming
  6. Pour required amount of HY-CLOR CloudOut Clarifier into the poolThis is used to help bind all small particles together so they are big enough to be captured in your filter, creating that crystal clear look.
  7. Add required amount of HY-CLOR EVO Mineral into the shallow end and brush thoroughly until no sediment remainsEVO Mineral contains magnesium and potassium to create softer and more luxurious water whilst helping to protect from scaling.
  8. While the chemicals are being circulated, brush the walls and floor thoroughly to kick up dirt and debris 
  9. Run the pool for 6 hours or overnight if necessary


Now your pool is ready for some long weekend fun. If you need any extra assistant regarding this procedure, contact the HY-CLOR 7-day helpline on 1800 625 123


Maintaining After Heavy Use

The long weekend has passed and now your pool is looking a little worse for wear. You may be wondering why this is? Well, this is due to heavy use or in pool maintenance terminology– “Bather Load”

Generally, any time there is an increased bather load in your pool it creates strains in the water. For example, if your pool endures consistent use throughout the week but an increased bather load on the weekend, higher levels of bacteria will be introduced into the water.

In these cases, the normal chlorine level is an insufficient amount of sanitisation, therefore creating a foggy looking pool. Let’s explain how to fix it with 3 easy steps:


Before anything, the first thing you want to do is backwash and rinse your sand filter or hose down your cartridge filter. That way, your filter is free to capture any particles for the next steps.

You will then need to test your chemical levels are within the ranges below:

pH: 7.2 – 7.6
Total Alkalinity: 80 – 120 (ppm)
Calcium Hardness: 200 – 500 (ppm)
Cyanuric Acid: 30 – 50 (ppm)


Once chemical levels are balanced, it’s time to shock the pool.

Before shocking the pool, make sure to brush the walls and floor to kick up debris clinging to the pools surface. For shocking a pool, there are many types of chlorines that can be used – we recommend using a calcium based chlorine like HY-CLOR Super Shock. Dosage rates below:

Stabilised Pool – 100g per 10,000lts
Unstabilised Pool – 150g per 10,000lts

Make sure to completely dissolve any granular chlorine in a bucket of fresh water before adding to the pool.


Now that you’ve tested and shocked your pool, the last step would be to add a clarifying agent to help with clearing the pool. Depending on the severity of cloudiness, any type of clarifier will do.

Once you have added the clarifier, make sure to run the filter for 24 hrs and clean the filter afterwards.

If you need any extra assistant regarding this procedure, contact the HY-CLOR 7 day helpline on 1800 625 123.

Quarterly Maintenance

Quarterly Maintenance

There are certain types of deep cleaning and maintenance that only need to be done 4 times a year. We suggest doing it at the chance of seasons to keep it simple.

Clean The Exterior Of The Spa

Get out a brush and the appropriate cleaning fluid for the material of your hot tub cabinet. Of course, you can clean the cabinet as necessary as possible – if it gets dirty or it’s starting to look grimy. Make sure you give it a thorough cleaning at least once ever season.

Drain and Clean

Drain the spa and do a deep clean on the entire shell. Take note of any damage like chips or cracks and call a professional if you need repairs. This is your chance to get rid of any chemical, mineral, or gunk buildup below the water level.

Refill and Balance

Refill the Spa and make sure not to overfill. When you have refilled the spa, test the water and balance until your alkalinity, pH and sanitiser levels are where they should be.

Soak Filter

While you are cleaning and refilling the tub – soak the filter in a cleaning solution. This quarterly soak will really get out the build-up of fine debris.

Annual Maintenance

Once a year, preferably around the same time each year you should do a full tune-up.

The following tasks should be done at least once a year. Remember, you can schedule your maintenance so that your monthly, quarterly, and annual maintenance fall on the same day.

Pipe Degrease

Flush all the plumbing lines with a spa pipe degreaser. This gets rid of bacteria and biofilm that builds up over time.

Check all the hardware and wiring.

Spas are usually pretty simple devices, but there are some components that can degrade over time. Weather, pests, chemicals, and everyday wear and tear can all take a toll. If you’re not sure what you’re looking at, bring in a spa maintenance professional.

Professional Inspection

Bring in a professional for a full tune-up. A pool maintenance professional will look at every aspect of your spa and make any necessary repairs.

Weekly Spa Maintenance

Weekly Maintenance

Once a week, perhaps on the weekend you will need to go one step further and spend about 20-30 minutes for your weekly maintenance.

Full Test & Balance

Test your water for alkalinity, pH, hardness and sanitiser. Make adjustments. Once a week you should adjust everything back to their ideal levels.

Shock the Spa

You can use chlorine-based or non-chlorine shock. HY-CLOR recommends using Spa Shock, just make sure to carefully follow the directions on the back of the container. Leave the cover off for a few hours afterwards.

Clean Spa Filtration

Remove your Spa filter and rinse it out with a garden hose. A clean filter will do a better, more efficient job cleaning your water.

Clean your spa cover.

Wipe down your Spa cover with a specialised cover cleaner. Clean the top and bottom. Dust can settle on the top of the cover and wiping it down weekly will prevent a buildup. Wiping the inside of the cover weekly prevents the accumulation of mold or algae.

Monthly Maintenance

Once a month you will need to do a more intense clean. You can coordinate your monthly checks with your daily and weekly checks to save time.

Extra Filter Clean

Rinse your filter with a specialised filter cleaner. Not every rinse needs to be with chemicals, but doing it once a month will clear out any excess dirt or grime.

Inspect Spa Jets

Assuming you use your spa regularly, you would notice if a jet wasn’t working correctly. However, take this opportunity once a month to purposely check each jet to make sure it is working and there is no external damage like cracks of loose parts.
