Hi all,
I've always felt that my pH wanted to rise too quickly but I never asked about it. I've been using the bleach/HCl method for a few years and recently switched to SWG. Since the SWG might have a tighter tolerance for pH I thought I would seek guidance. I lowered my pH with acid just recently. pH in 8/5 was between 7.4/7.6, on 8/6 was 7.6 and this morning was 7.8. That seems to fast to me. The VSP running at 2250 RPM for 12 hours/day and the SWG was running at 60%, but I just lowered it to 50% since the chlorine was still climbing over when I was using bleach. Anyone have some insight? it's been this way for years. The pool really likes to be around pH 8 or 8.2. New plaster is about 16 months old, but I had the same problem with the old plaster too.
Here's the full set of water parameters. I know CH is low, but the CSI is fine so I haven't upped it and I know CYA is low for SWG, but the generator is keeping up, likely due to some shade on the pool.
Temp: 86, Chlorine: 7.2, CYA: 30, pH: 7.8, TA: 80, CH: 260, Salt: 3600
