Can I ask I beg for some help regarding my continually increasing pool PH? The plaster was replaced 1 year ago, I had it acid washed 2 months ago (scale staining I think).
Well, my PH rises at 0.1 every day, requiring 12 oz of acid daily. ChemGeek suggested that I lower the TA, and running the ph 7.6+. I did this, TA was 70, and over several weeks has drifted town to 50. Not much change in the acid demand in the pool. The other odd thing, is without any addition of water, my CH has risen from 280 to 320.
Should I be worried?
Is the pool still curing (and sort of recurring from the acid wash)?
I used the pool calculator--my csi runs a bit negative, should i go ahead and increase the TA?
TA 70 (now 50)
