Since I've switched to BBB method things have been going along well. The pool is beautiful and the kids are having their friends over again! However, I have some questions about pH.
I treated with borax, adding 1/2 last night and 1/2 the night before. 19 boxes borax and 5 1/2 gal MA in total. So yesterday morning the pH was only off by a little, but this morning's acid demand test called for a gallon of MA. I added that early, then by noon tested again and it called for another 2 1/2 qt! How is it I'm needing so much acid? I know I used the right amount with the borax.
Today's test results:
The pH is too high to measure. I added 25 lb calcium chloride the night before the borax, if that makes any difference. Did the borax cause this rise in my TA? Is the higher TA what's giving me trouble with the pH?
I've been reading BBB for Beginners. The thing I don't understand about lowering my TA is this. Why do I aerate to raise my pH? That's what my whole problem is!
