I have been scouring my carpet and stuff around my tank for weeks now, all seems dry. All sump fittings, not a drop. My question is what is a normal evaporation rate? I lose between a pint and a quart a day right now. My house is at about 72, and 32% humidity. Between last night and tonight I added almost a gallon, but I went up a little extra in the sump because I'm tired. Is this normal? I do have a lot of turbulance at the water surface, two Korillas, a 2 and a 3, spray bar from the sump and a canister eheim also.
