A Theory About Rising pH in SWG Pools

[klharmon]

I go through about 1/2 gallon a week of muriatic acid on my 19,000 gal in ground pool, and I have an AquaPure 1400 SWG. I have a waterfall feature that I use rarely, so a majority of the time the pool just vacs & filters.

pool is relatively new, plaster bottom, and I check pH twice a week.

What's your TA, CYA and pH?
