I've been using Cal-Hypo 73% for Chlorine, as I needed to raise CH. I just reached 350 CH, so switching over to 10% bleach.
pH has been drifting a little. I'll start it at 7.7. Over about 3 days, it will reach 7.9, at which point I put in about a quart of HCl, taking it back to 7.7. TA had been about 70, but is down to 60. Borates are right around 30. I ran out of Borax and the Boric acid arrived but I haven't put it in yet...
My backyard has only low fruit trees and a nearly constant breeze. Someone mentioned this might be driving the TA/carbonates down with CO2 loss and affecting pH.
I'm contemplating adding some baking soda to get back up. Will this help with the pH drift? Is this pH drift relatively normal?
My acid use is "minimal", maybe a gallon every 2 weeks.
