Hhhmm. Is there a non-liquid pure chlorine format that I can use instead of bleach? The granules seemed easier to store and apply than liquid jugs of bleach, and I'm not sure the bleach is cheaper. My pH has been a steady 7.5, and I had been adding about 1/2 cup of granules every other evening to keep the OTO dark yellow. The SWCG runs for 4 hours at night.

And if I go a pure chlorine route, how much more CYA should I add? I had been doing a pound at a time via the sock method, until I had added the full 4 lbs ... I don't remember how much that raised me to, I can't find my notes. We have had rain this summer, unusual for Texas, so I know I lost some CYA from pool overflow.
