OK, I have a 25,000 gal gunite pool. Just at the tail end of opening. Water is clear after 6 days of 24/7 filter and at least 20 gal of bleach over that time to keep my CL levels up to clean up the green. Current reading are:
FC - 3.5
CC - .5
pH - 7.2
CYA - 0
ALK - 130

So I was assuming my next step was to get my CYA up. But I'm looking for proper direction at this time. (and exactly what product to purchase to do it) thanks
