hmm any indoor gardeners on the board?

I guess the 5 gallons dosent make much of a difference, my friends fish room evaporates about 50 gallons everyday and he has similar problems as me, I can evaporate 150 gallons a day depending on the weather, and when our new fish room is setup, I think we might evaporate up around 200-300 gallons a day, there will be alot of surface area of water
