From Pool Math: Note: Dichlor and trichlor add CYA and lower pH. How much CYA? I have dichlor bags to use up (when my CYA gets low , not now); 99%, available Cl 55% Second question Can you suggest a pump RunTime ( # of hr per day) based on the info in my signature, I know it varies by...

Thank you very much. No SWG Definitely not 14 hours of sun, so we’ll be lowering. Target CYA 60 by lowering the water 33%-40%, I’ll go with 40%. Should be good to go then & will re-test TA & pH after the refill. Thanks again

Lowered the water 50% or a tad more because CYA was over 100, maybe over 200/250. Recirculated for >24 hours 4.9.2021 test results CYA 90 (90-100, read it several times, I'm more comfortable with 90) pH 6.8 or less but darn close to 6.8 IMO FC 6.5 CC 0.0 TA 90 CH- not tested, vinyl...

Thanks, did that, it looks nothing like JohnnyB's PoolMath on his Laptop, what am I missing? He can help me better if its like his. I too am on a desktop/laptop. Thanks

Thanks, Yes JohnnyB will help me go thru pool School. Are we correct that we need not test or treat CH for my vinyl pool (Johnny has plaster)

New to TFP. But JohnnyB is helping me. First test 3.20.2021 630PM pH 7.2 FC 33.5, been using bags of shock from pool store CC 0.5 TA 240? CYA >100 Added pH up this afternoon- Johhny B will coach me in the future We ignore pH reading while the FC is so high, right? We re-test pH once the...
