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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is my pH dropping after using Trichlor?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I put tablets directly in the pool?\u003c\/strong\u003e\u003cbr\u003eA: No - never place tablets directly on pool surfaces. The concentrated chlorine can bleach and damage vinyl liners, fibreglass, and concrete.

A 50,000L pool typically uses 2-3 tablets per fortnight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will Trichlor tablets affect my pH?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use these in a saltwater pool?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is cyanuric acid and why does it matter?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Where should I put the tablet?\u003c\/strong\u003e\u003cbr\u003eA: In the skimmer basket, an inline chlorinator, or a floating dispenser.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is my pH dropping after using Trichlor?\u003c\/strong\u003e\u003cbr\u003eA: Trichlor is slightly acidic (pH approximately 2.8-3.5). Regular use will gradually lower your pool pH. Test weekly and use pH Increaser (Soda Ash) to maintain the ideal 7.2-7.6 range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I put tablets directly in the pool?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between Trichlor and Dichlor?\u003c\/strong\u003e\u003cbr\u003eA: 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.
