In this guide on chemicals for pool cleaning, you’ll discover the key chemicals for maintaining a pristine pool. From chlorine to pH balancers, we’ll explain what they do and how each will keep your pool in top shape.

What Do I Need To Keep My Pool Clean?

Algaecides

Algaecides are specialised chemicals designed to combat and prevent algae growth. These microscopic plants will turn your pool green and make your pool steps slippery and unsafe.

Algaecides break down the cell walls of algae, making it easier for your pool’s filtration system to remove them.

In the big picture of pool cleanliness, algaecides act as a supportive player. Use them along with other chemicals for pool cleaning to maintain a completely healthy and clear pool.

Balancer Chemicals

Balancer chemicals adjust the acidity, alkalinity, stabiliser levels and hardness of pool water, enabling other chemicals for pool cleaning (like chlorine and algaecides) to function effectively. They also prevent damage to your pool and equipment.

Balancer chemicals include:

  • Alkalinity increaser
  • Calcium increaser
  • pH decreaser
  • pH increaser
  • Stabilise

Alkalinity increasers raise pool water’s total alkalinity, creating a more stable pH environment when the alkalinity level is between 80-120ppm.

Calcium hardness increasers add calcium to your pool water, which is essential for preventing foamy water and protecting your pool equipment from corrosion and scaling. Most pools require between 250-500 ppm. This prevents the water from trying to leach it from elsewhere. Please note that a mineral pool will show high Hardness due to the way testing for total hardness is done.

pH increasers elevate low acidity levels to avoid swimmer skin irritation and damage to pool equipment. Meanwhile, pH decreasers lower high alkalinity, allowing chlorine to be more effective, deterring cloudy water and calcium deposits. The ideal pH level for most swimming pools is 7.2 to 7.6.

Clearly, well-balanced water helps you dodge a whole host of problems!

Chlorine Sanitisers

Chlorine sanitisers act as disinfectants, killing bacteria, viruses, and other microorganisms in pool water. They’re the primary line of defence in maintaining a clean and safe pool.

Swimming in unsanitised water can expose swimmers to various health risks like bacterial infections, viruses, skin and eye irritation, and ear infections.

Chlorine sanitisers are available in tablet, granular, and liquid form.

Chlorine levels are typically kept between 1-3 ppm.

Clarifiers

Is your pool cloudy? Cloudy water can result from poor filtration, imbalanced water chemistry, or fine particles and contaminants your pool filter can’t catch.

If it’s the latter, you need pool clarifiers. Clarifiers work by clumping tiny, hard-to-filter particles into larger ones, making it easier for your pool’s filtration system to remove them.

Flocculents perform a very similar function to clarifiers but are more effective when your pool water is very cloudy. Flocculent particles are bigger and heavier than clarifier particles and as a result they do not get filtered through the filter system, but instead sink to the pool floor where they need to be vacuumed to waste.
Whether you are using clarifiers or flocculents, your cloudy water will transform into crystal-clear water in no time!

Pool Salt

Chlorine sanitisers act as disinfectants, killing bacteria, viruses, and other microorganisms in pool water. They’re the primary line of defence in maintaining a clean and safe pool.

Swimming in unsanitised water can expose swimmers to various health risks like bacterial infections, viruses, skin and eye irritation, and ear infections.

Chlorine sanitisers are available in tablet, granular, and liquid form.

Chlorine levels are typically kept between 1-3 ppm.

Specialty Chemicals

Shock

Shock treatment for chlorine pools rapidly elevates chlorine levels to break down organic waste, bacteria, and algae.
Shocking your pool also removes chloramines. Chloramines are formed when free chlorine is used up and becomes combined chlorine. When chloramines build up, your pool has a strong “chlorine” smell and your free chlorine is not as effective.

You might need to shock your pool after heavy usage, a storm, or when you notice algae or cloudy water. Shock treatment is your go-to for heavy-duty cleaning, hitting the reset button on water quality.

Stabilsers

Stabiliser, usually made from cyanuric acid, protects chlorine from quickly degrading by sunlight. It acts as a shield, making chlorine last longer in your pool. Without a stabiliser, your pool would require more frequent chlorine doses, costing you time and money.

Using a stabiliser helps chlorine remain effective longer for a cleaner, healthier pool.
Hy-Clor offers stabiliser in tablet or granular options

Stabliser/Cyanuric acid levels are typically best kept between 30-60 PPM.

What Spa Supplies Do I Need To Keep My Spa Clean?

  • 1
    Sanitisers: Chemicals like bromine or spa chlorine tablets disinfect the water by killing bacteria and viruses. Bromine works best for a heated spa however breaks down rapidly in the sun , stabiliser can’t help bromine.
  • 2
    pH balancers: pH increasers and decreases adjust acidity and alkalinity levels, ensuring sanitisers work correctly.
  • 3
    Alkalinity boosters: These increase the water’s alkalinity level, providing a stable pH environment.
  • 4
    Calcium increaser: Adds calcium to the water to prevent foam and protect spa equipment from corrosion.
  • 5
    Shock treatment: The ultimate spa cleaner, this concentrated dose of sanitiser rapidly oxidises contaminants and rejuvenates water clarity.
  • 6
    Clarifiers: These help coagulate tiny particles for easier filtration, improving water clarity.
  • 7
    Spa fragrances: These not only add pleasant scents to enhance your spa experience but often contain clarifying agents to help improve water clarity.
