Thanks! The PH is 7.2 I put in 3qt (96oz) as you said, and will add the stabilizer soon.
I am excited to have a fighting chance at a clear pool this summer. It will be the first summer in 5 years of pool ownership that I have an arsenal against algae. I found this site out of desperation last August and had the best water around for the end of the season. Problem was easy to guess, my CYA was off the charts.
