Interesting about the bromine floater outgassing, I should look into that. The only thing I was told was not to have the air on while the cover was on and the pump running as that could cause premature wear on the cover.

On a sidenote, I have to empty my softtub soon, would it be ok to empty the 300 gallons into the pool??? The pool holds approx 14,500 gallons and is an SWG pool. The softtub is bromine, is there the potential for a chemical problem???
