OK, now what did I do wrong? After last post, I was attempting to raise CYA from 27 to around 40, so I added stabilzer (approx 2lbs to start, then will recheck in a couple days), also added 3 jugs bleach to raise Cl from basically nonexistent and finally bring the pH from 7.0-7.2 range up to 7.4, so I added half a box of borax . Planned to see what level was today then add the remainder of box if it didn't get up to 7.4 with the amt given by calculator (which was 2.7lbs, which is about what I added). But today, when I took a reading with the quick check, my CL level was good, but pH was even lower....barely an orangish color in the 6.8 range! What happened? I thought Borx would raise, not lower pH. Had about 1/4" of rain last night, if that matters..
Levels before I added above chems (I added and waited a few hours between additions):
FC = 1.5
TC = 2
ph 7.0-7.2 (still can't distinguish to well yet!)
What is my next step? Have an above ground vinyl, 22,500 gal, no SWG, use BBB
