Hello all! I'm curious how you handle maintaining your pool while on vacation for a week? How do you ensure chlorine levels stay up and you don't have an algae outbreak or something else? If I filled the "floating duck" with chlorine tabs, how much would I see my CYA increase? We are at 40 for CYA and have an 11,500 gallon pool. We had to empty 3/4 of our pool to get our CYA down at the beginning of summer and I am scared to death of having to do that again.
