I've been trying to 'zone in' with my test numbers. The obvious thing is that when I really hit the pool with the bleach it really cleans and clears it up. Now I know the trick is getting the CYA to buffer the bleach and that's where I seem to be falling down. I took it up to shock level over the weekend and did an overnight loss test and it seemed to hold OK. My test this a.m. showed virtually no FC so I added 80 oz. (5pt) of bleach and got
pH is low <7.2
I added Borax ~ 3# to help the pH. What should I really focus on so that I can get to just adding daily small doses of bleach vs. having to hit it in 'shock' mode.
Tx so much,
