I have a 25,000G above ground pool. What would cause the pH to keep climing? My recent readings last night are:
pH 7.8 (was 7.4 2days ago) No water added, no rain. Shocked with Ca++ hypochlorite once the night before this reading.
I use 10% liquid chlorine. Don't use algecide. Water was crystal clear but has just a very little bit of cloudiness now...shocking didn't help. Is the pH causing this? Why would the pH clime?
