Dosing Guide
- Use 1 tablet per 20,000L of pool water
- Replace every 1-2 weeks as the tablet dissolves

- Never place tablets directly on pool surfaces - can cause bleaching and damage
- Target chlorine level: 1-3 ppm for swimming pools
- Test weekly with test strips to confirm chlorine levels are maintained
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.
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
- 5-Pack (1kg) - ideal for trying Trichlor or small pools.
- 10-Pack 2kg (this product) - great for smaller pools or seasonal use.

Frequently Asked Questions
Q: How long will a 2kg pack last?
A: For a 40,000L pool using 2 tablets per fortnight, a 10-pack lasts approximately 10 weeks. It's a solid choice for smaller pools or as a seasonal supply.
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.
