I have been struggling with keeping my pH from rising quickly. I can lower it with MA to 7.4 and then within a couple of days it is back to 8.0. I am told that new plaster pools have this issue.
This morning around 7 am the pH was at 7.4 and this evening at 7 pm it was already back up to 7.8.
Is there anyway to slow this down so I only have to add MA once per week? or even twice per week instead of daily?
The latest readings were:
FC= 4 CC = 0 pH=7.8 Acid Demand =1 TA=70 CH=390 CYA=60.
