Frequently Asked Questions
Q: How many tablets do I need per week?
A: One 200g tablet per 20,000L of pool water, replenished every 1-2 weeks as it dissolves. A 50,000L pool typically uses 2-3 tablets per fortnight.
Q: Will Trichlor tablets affect my pH?
A: Yes, Trichlor is acidic and will gradually lower pH. Test weekly and use pH Increaser (Soda Ash) to maintain 7.2-7.6. This is normal and manageable with regular testing.
Q: Can I use these in a saltwater pool?
A: Yes, Trichlor tablets can supplement a saltwater chlorinator during high demand periods. Monitor cyanuric acid levels closely as they will rise faster in combination use.
Q: What is cyanuric acid and why does it matter?
A: Cyanuric acid (stabiliser) protects chlorine from UV breakdown. Trichlor tablets contain stabiliser, so levels build up over time. Keep cyanuric acid between 30-80 ppm. Above 80 ppm, chlorine becomes less effective.
Q: Where should I put the tablet?
A: In the skimmer basket, an inline chlorinator, or a floating dispenser. Never place tablets directly on the pool floor or steps as they can bleach and damage surfaces.
