Yes, I read about that too late….! I bought a bunch of "stuff" from my (former) pool store guy before I found The Forum... 25 lbs of pH up is what they recommended. My pool's pH has been low all season, however TA has been about 80-100 level (until just recently it went up to 120). I still have 10 lbs left so I thought I'd use it up. Didn't realize it had extra stuff in it. I'll get Borax for next time.
thanks for the info.
