I added borates to my pool last week hoping it would help my battle with rising PH with it's buffering properties, I was wrong. I checked my PH and it has gone from 7.6. to 7.9 in the matter of a few days.Without intervention the pool will usually top out at around 8.1-8.2ph.
My TA was 90 before adding borates, after adding 50ppm of borates it is has gone to TA of 100. In a few weeks time I am sure that TA will drop with all the acid I put into the pool, after a few months I usually have to add baking soda to get it back into spec. My jets look fine, no air bubbles or substantial bubbles in the pump basket so I don't think it's an aeration problem.
So my question is what other ideas can I do keep this PH battle more stable?
