Chlorine Tablets: The Hassle-Free Way to Keep Pool Water Clean

No one wants to spend their weekend measuring chemicals or scrubbing algae from the pool. That’s where chlorine tablets come in. These slow-dissolving tablets provide a consistent, reliable dose of sanitiser, keeping your pool crystal clear and safe for swimming. They make pool maintenance effortless and stress-free.
At Hy-Clor, we supply premium pool chlorine tablets that provide a cleaner, healthier pool without the daily upkeep. Discover why these tablets are a smart addition to your pool care routine.

What Are Chlorine Tablets?

Chlorine tablets are compact blocks of stabilised chlorine, made from trichloroisocyanuric acid. Their stabilised form resists breakdown from the sun’s UV rays, making them ideal for Australia’s bright climate.
Unlike liquid or granular chlorine, these tablets dissolve slowly over several days, ensuring steady chlorine release to maintain balanced water chemistry and protect against bacteria and algae.
Easy to use, they can be placed in a floating dispenser, or automatic chlorinator, working continuously to save you time and effort.

Why Use Chlorine Tablets for Your Pool?

Chlorine tablets offer several benefits over other options:

  • Convenience
    There’s no need for daily dosing or messy measuring. Pop the tablets into your chosen dispenser and let them handle the sanitising for you.

  • Long-Lasting Power
    Their slow-dissolving design means they last longer than liquid chlorine, which can dissipate quickly, or granular chlorine, which needs to be added more frequently.
  • Consistent Sanitisation
    Because they release chlorine steadily, you’re less likely to experience sudden drops in chlorine levels that can lead to cloudy water or algae outbreaks.
  • Compact and Easy to Store
    Chlorine tablets for pool care don’t take up much space and are safer to store than bulky containers of other types of chlorine.

  • Protection Against Sunlight
    All Hy-Clor tablets are stabilised to resist breakdown from UV rays. This means your chlorine works harder for longer, even in direct sunlight.

Still wondering, are chlorine tablets better than granules or liquid chlorine? The answer often comes down to convenience and consistency: for regular, easy sanitising, tablets are tough to beat.

How to Use Chlorine Tablets Effectively

Here’s a simple guide to getting the most from your chlorine tablets:
Step-by-Step Guide:

Pick the right dispenser:

Use a floating dispenser or automatic chlorinator. Never place tablets directly on the pool floor or ledges to avoid fading or damage. Never place them in the skimmer basket either. The high concentration of chlorine that gets sucked into your pump and other pool equipment will cause damage over time.

Use the right amount:

Generally, add one 200g tablet per 20,000 litres of water weekly. Adjust based on pool size and test chlorine levels regularly with a pool test kit or test strips.

Check levels often:

Keep chlorine levels between 1–3 ppm for safe, clean water. Test weekly, or more often during heavy use or hot weather.

Safety Tips

  • Always handle chlorine tablets with dry hands or wear gloves to avoid skin irritation.
  • Keep them in a cool, dry, well-ventilated area, stored away from other chemicals.
  • If you have young children or pets, store tablets out of reach.

FAQs

Do Chlorine Tablets Kill Algae?2025-07-08T12:47:21+10:00

Yes. Used consistently, chlorine tablets help prevent algae growth by maintaining a sanitised environment. For severe algae blooms, pair them with an algaecide and shock treatment for best results.

What’s the Difference Between Stabilised and Unstabilised Chlorine Tablets?2025-07-08T12:46:19+10:00

Stabilised tablets contain cyanuric acid to protect chlorine from sunlight, making them perfect for outdoor pools. Unstabilised versions are best used for indoor pools or quick boosts of chlorine. Hy-Clor does not offer unstabilised tablets. For unstabilised chlorine use liquid chlorine or unstabilised granular chlorine.

How Long Does It Take for a Chlorine Tablet to Dissolve?2025-07-08T12:43:40+10:00

Typically, a standard 200g tablet dissolves over 5–7 days, depending on water flow, temperature, and placement.

Can Chlorine Tablets Damage My Pool Liner?2025-07-08T12:43:23+10:00

When used correctly, no. Never place tablets directly on your pool’s surface. Always use a floating dispenser, or chlorinator to avoid fading or damage.

How Many Chlorine Tablets Should I Use in My Pool?2025-07-08T12:42:01+10:00
