Personally, when I was doing bleach, I controlled pH with muriatic acid. Simple and easy. No worries about how much CYA I was slamming into my pool with the tablets. I like adding one thing at a time, in quantities that I know about. That's what makes it easy to keep a pool in balance.

So you don't use chlorine pucks at all? You just use bleach for normal chlorination?
