Thanks so much for your help! My kids and I looked over the entire ring and couldn't find where it was leaking from. My husband came home, looked it over, and found 3 holes! He patched them up and it looks to be holding air.

We'll fill to 6" tonight, I'll add 2 doses of bleach in then. Finish filling tomorrow. When should I add CYA and what dose?

We can't return the pool Bought it from a garage sale from a couple who put it up for 2 summers, but said it was rarely used. We knew we were taking our chances.
