Hello,
I have been using bleach as our chlorine source since we moved into our new home a couple of weeks ago. Water continues to look clean and clear, but I've noticed that the pH reading has climbed slightly during that time (I use TF-100). PH was at 7.2 back on 6/1, and has since steadily gone up to 7.8 as of this afternoon. Wouldn't be as concerned about it if our CH wasn't so high (previous pool man used cal hypo once a week to shock). Below is a full set of numbers:
FC = 8.5
CC = 0
PH = 7.8
TA = 80
CH = 860
CYA = 100
I just added enough bleach to raise FC to 10 based on our high CYA. 10 seems to be working well for keeping water nice and clear. We're expecting heavy rainfall this evening and over the next couple of days. Just wondering if I need to be lowering pH, or if it's fine for now.
