Last week when I checked PH it showed almost 8.5 or even higher, pinkish color. Immediately, started adding MA, 28 oz first day. Tested again the next day and still high pinkish color, so added another 28oz.
Third day PH showed the same and then I tested TA, which showed 120 for a semi salted cemented pool (water is salty due to using liquid Chlorine for the past 3 years), 12,500 gallons pool.
So far I have added 128oz of MA, 12.5%, I think from HASA, and the TA only dropped to 105-110 range, PH dropped to 7.3ish range. Temps are hovering around 110 to 118 for the past 20+ days, going down a bit and pool is running 10 hrs a day and is aerated daily.
Whenever my PH was high, it took few days to get is under control, but for some reason this time its taking a lot of MA.
Anyone can give me pointers on what I am missing?
