Alkalinity

I faced a similar problem with fill water from a truck at one of my clients, as I recall TA was 360 or thereabouts, pH above 8. I eventually brought it down to 80-100 ppm with constant additions of pH-. Keep it down else you risk scaling at the waterline.

Cal Hypo doesn't raise TA it raises CH.

My pool is an in-ground, gunite or concrete with palster. It's shape is like a two-ball snowman and the end being lager. It's 32 feet long X 16 feet on deep end and 18 feet at shallow end. The depths are 3.5 feet shallow end and 8.5 feet deep end; so my guess is it is 25,000 gallons. My CYA is 100-120PPM and water temps in the lower 90s, so I'm trying to keep FC between 8-12PPM. I really appreciate the help and my pool has really been look great, good color and clarity.
