Hi.
I've successfully used TSP method on my pool the last 2 years - going from green (thanks to Loop-Loc cover) to clear and eliminated all problems during season with lower chlorine usage and filter run time.
I am helping a wife's friend (divorcee with no help) get her pool started this year - had a cover blow off and never reinstalled so big time green. Above ground 7,500 gallon pool (much smaller than mine).
Started the shock process last Thursday - so going on 5 full days. Cleared green in 3 days...working on extreme cloudy condition now.
When I started, CYA registered below 20 (can't measure with TFT100 kit then) but didn't concern myself with it.
Pool is mowing through chlorine still - 2ppm loss per hour in sunlight. While clearing cloudiness, I'm sure some loss because of CYA deficient.
Should I go ahead and adjust CYA...or wait until we get clear water?
I have been targeting 10ppm for shock process. CC started at 1.5, and is now 0.5.
I'm leaving Friday at which time she'll be on her own for a week....would like to do the best thing I can to have her at / near success if any suggestions.
Thanks.
