Hi Folks:
Prepping for my close on Monday. I've got a 32K gallon gunite in ground pool. I see from the "How to close an unground pool" sticky that they recommend SLAMing the pool a few days before and also getting most of the chemistry dialed in with PH "between 7.4 and 7.6".
I've got a gunite pool. Right now by PH is a bit high....8.2ish. But when I'm in pool math and current water temps of 60 degrees the CSI is balanced almost perfectly. Lowering the temp to the 50s or 40s is still balanced.
If I model lowering the PH to 7.4 the CSI drops with the "potential to become corrosive."
So my question is how important is PH when you close? Poolmath seems to think higher is better with colder temps.
