A couple of readings from when I first got the house about a year ago:
2/22/14 PH 8+, TA 80, CH 360, CYA 60, FC 0
5/17/14 PH 8+, TA 70, CH 380, CYA 58, FC 0
I have been putting only liquid chlorine and muriatic acid. I have been struggling with the high PH. I have a spa spillover which I understand is contributing to the high PH. My FC does not seem to hold very long even with a decent CYA level, and it is often zero when I check.
Today, about a year later, I did a full reading and got:
PH 8+, TA 90, CH 220, CYA 0, FC 0
So what has happened to make my CYA disappear?
FYI: Yesterday for some reason I decided to shock the pool (8k gallons) with 0.75 lb. of potassium monopersulfate. I regret it and will not be using it again. I will be sticking with chlorine. Could that powder oxidizer have affected my readings?
I have a swarm of kids coming tomorrow for the weekend. How can I get the CYA up quickly for the chlorine to hold? The pool is in the hot SW FL sun.
