Hi - big fan of TFP and really appreciate the expert advice here....
Just checking before I close the pool this weekend.
pH = 7.8
CSI = 0.0 (Poolmath)
FC = 5.4
CC = 0.0
CYA = 30
I know ideally CH should be higher but I've kept it this way because the previous owner left a lot of calcium deposits on the surface of the plaster.
Another factor is that the pH in this pool always wants to climb to 7.8 - 8.0. I have repeatedly tried muriatic acid and dry acid, which reduce pH, but after a few days it just climbs back up to 7.8 - 8.0!
What are the risks of leaving the water as is for the winter (covered with mesh safety cover)?
