my TA is 220, yet PH 7.4, FC 4, CYA is high 120, CH 230, 10k gallon in ground fiberglass pool, had been use BBB method for past few months, and I used cholrine granules 3 times in past 2 months as FC levels dropped below 1.5, 2-3 oz at a time just to spike it back up, unusal warmer weather burning off bleach quickly
Also I was using roman fountains I have in pool, jets on, ran for 7 hrs, went checked on it and water was all milky colored, is that just alot of air being added to water, it cleared in about 45 min after I turned off fountains and just ran jets, pump, filter. New filters added this MArch and checked, soaked and cleaned just before labor day
I believe I need to drain about 60-70% of water to get CYA lowered,
Also top and second step into pool are discolored to tan tint partially both on same side, and floating thermometer has a sticky light brown residue on submerged end, water is very clear I've used some algecide last 4 weeks, but no change.
Hate going to pool store, as been fooled before, hopefully some of you guys have some answers. thank you
