22,000 gallon vinyl pool
What chemical could the pool store have put into the pool that could use up 19.5 ppm of FC in less than 3 hours at night?
There is not one sign of algae or bacteria in this pool and yet it will not hold FC. The store came by and rail roaded this guy, and then told him he was going to have to shock his pool to 80ppm. Suffice to say he told them to get lost not before they to got $650. He heard about me and asked me to check things out. Bean slamming for about a week now ti get rid of CCs, Ran the overnight test last night and results were less than stellar, as you can read.
The reason i believe they may have added something they shouldn't was their comment about shocking it and the cya being at 400 or something.
Anyway, truly the pool looks tremendous but chemically, not so good.
