Hello I am new to the forum. I have a 22,000 gallon fiberglass in ground pool with a hayward sand filter. Early in the season I realized I had a high CYA due to the puck style chlorine tablets. I have since switched to Bleach. After three partial drain and refills I have lowered it to 65. Not ideal I know but i'm trying to make it work until the winterization next month.
The problem I am having is I have added 50+ pounds of CH+ and only raised the Ch level by 50. And seems to vary thru the day. I have a brand new color q digital tester and have been testing daily. My levels are as follows.
I feel like I have been missing something here. Also wasting money possibly @ 60.00 in Ch+ alone. Any help or ideas would be greatly appreciated. Thanks in advance T
