I decided to add borates to my pool today, and started off just fine. I manually chlorinate with 12.5 chlorine. Before I added borax I had TA of 110 and Ph of 7.4. My pool is 10k gallons. First I added 150 oz. Of muriatic acid then 4 boxes of borax. I swept the pool then added another 150 oz of acid and another 4 boxes of borax. Now after several hours I noticed my ph was quite high so I added some more acid, which shouldn't have made as huge of a jump as it did because it pushed it to around 6.8. At this point I decided I should recheck my TA. TA is now at 40. Before I start slingshotting everything back and forth, I figured I would come here and ask first.
