99% Tri Chlor which is great

The tablet holds the ORP good. 99% Tri Chlor which is great compared to others. I use 2 per week for 20,000 gallon pool.

I have been using this chlorine for years until last year when I bought a different brand. HTH is much better than any other brand that I have used because it dissolves faster and does a better job of sanitizing the pool water.
