Have been self managing our pool/spa combo for over 10 years. Until the recent (2 months ago) replaster, was using chlorine tabs with an inline feeder (yes, CYA was always high) and the pH as well as other chems were very steady. pH stayed around 7.3-7.4 during the summer with no help needed. I would add MA during the off season to keep pH below 7.8, due to chlorine tab disolve rate being lower because of lower water temps. After finding TFP this spring, I've switched to liquid bleach and no tabs.
Immediately after the replaster two months ago, I was adding 28 oz MA daily to keep pH down around 7.2-7.5. After advice from others, I've let pH float up to the 8.0 range. I'm now adding 16 oz MA daily to lower pH each morning from 8.0 to about 7.8. I've been locked here for several weeks. Spillway is on 2x/day only to keep water chemistry the same. TA is 70. See my logs for other details. Fill water is pH >8, TA 50. Any way to mitigate the acid demand? Does it just take lots of time for the plaster to cure? This is making travel/vacation very difficult to manage!
