Tip: Trichlor tablets work best as your baseline ongoing chlorination. Pair with Crystalline Chlorine (Dichlor) for shock dosing after heavy rain, high bather load, or when chlorine drops quickly.
Important: Never place tablets directly on pool surfaces - concentrated chlorine can bleach and damage vinyl liners, fibreglass, and concrete. Always use a skimmer basket, in-line dispenser, or floating dispenser.
Trichlor vs Crystalline Chlorine
- Trichlor Tablets. Slow-dissolving, set-and-forget baseline chlorination. Best for ongoing maintenance.
- Crystalline Chlorine (Dichlor). Fast-dissolving, ideal for shock dosing and spa use. Best for top-ups and reactive treatment.
- Best practice. Use both - Trichlor for ongoing baseline, Dichlor for shock dosing when needed.
Available Sizes

- 10-Pack (2kg) - great for smaller pools or seasonal use.

Frequently Asked Questions
Q: How long will a 10kg bucket last?
A: For a 40,000L pool using 2 tablets per fortnight, a 50-tablet bucket lasts approximately 50 weeks.
Q: Can I use Trichlor tablets in a spa pool?
A: No - Trichlor tablets are not recommended for spa pools. The smaller water volume and higher temperatures cause cyanuric acid to build up rapidly, leading to over-stabilisation. Use Crystalline Chlorine (Dichlor) for spas instead.
Q: Why is my pH dropping after using Trichlor?
A: Trichlor is slightly acidic (pH 2.8-3.5). Regular use will gradually lower your pool's pH. Test weekly and use pH Increaser (Soda Ash) to maintain the ideal 7.2-7.6 range.
Q: Can I put tablets directly in the pool?
A: No - never place tablets directly on pool surfaces. The concentrated chlorine can bleach and damage vinyl liners, fibreglass, and concrete. Always use a skimmer basket, in-line dispenser, or floating dispenser.
Q: What is the difference between Trichlor and Dichlor?
A: Trichlor is slow-dissolving and ideal for ongoing baseline chlorination via a dispenser. Dichlor (Crystalline Chlorine) is fast-dissolving and ideal for shock dosing and spa use. Most pool owners benefit from using both.
