I’ve had an issue keeping our Ph down this year. Personal preference is on the high side so try to keep it at 7.7 to 7.8.
Pool math usually has me adding 1 or 2 cups of MA at a time to lower ph. Two days later I have to add more. Last year I used a gallon of MA all year. This year I’ve already used 3 gallons.
Last night I put in .5 gallon of 31.45% MA to see what would happen and how quickly ph will rise with aeration from return jet eye. Ph went from 8.0 to 7.4, as it should have. (TA stayed at 70, which surprised me a bit as our water is usually pretty sensitive for TA when Borax or Baking Soda is added.)
We repainted the pool this spring. Used same brand we did 6 years ago, but different color.
Fill water test at start of year was same as last year (I’ll retest.)
Could the fresh paint be what’s causing the ph to want to be 8.0+?
If so, will this eventually settle down?
Any other thoughts appreciated.
