I have a Rainbow tab feeder on a 10,000 gal pool and I have it set on 4 (goes to 5) and it is not keeping up. The CYA level is 50.
1st night 8.5
2nd night 5.5
3rd night 3.5
I will bump it up with liquid chlorine and am just trying to use my chlorine tabs up. Plus, I am trying to get a feel what to set the tab feeder on when I go on vacation.
