It is nice to be back on the forum. Opened my pool a few days ago and my PH level has dropped from 7.5 to 6.8 during the winter months (may be even less based on kit). I added the remainder of Borax to raise the PH. Last year, my TA was at 120 and I managed to bring the level down to 100 (prior to closing). Because I had constant rising PH levels (requiring acid additions every 4 days), I decided to pump the winter water on the cover back into the pool. It appears that the TA has dropped to around 70. Will test again tomorrow.
At moment,
TC = 8
CC = 0
CYA = 50
TA = 70
CH = 175
With the PH being at 6.8 or even 6.6 (not sure), does this pose any threat to the liner, corrosion and staining? It is real important to bring the PH back up quickly, or should I aerate and bring up slowly? Please advise!
