new semi in-ground vinyl pool 15x24, 54"deep, 13,350 gal. started out with pool store advice, until i found this forum which i'm very grateful for. the pool store advice was setting me up for a CYA saturation, thanks to this forum i was able stop before it got real bad. these are the results form the tf 100, pool school recommend CYA 30-50 except in extreme sunlight, what is considered extreme sunlight? how many hours of sun?
cya 65-70 would have been worse if not for this forum thank you all, i love liquid bleach wal mart 8% 3 bucks a gal.
pool is crystal clear
