I have been using these stupid tablets from costco instead of bleach in my pool and was told here to stop as my CYA would climb. I just tested and indeed it did steadily week after week. It is now at 90 and should be at the highest at 50.
What does this CYA do?
Anyway I have an above the ground pool and pool calculator tells me I have to replace 44% of the water. That is some task!!! How do I do that?
Thanks for the help
