Ahh. Well yes, warmer water does evaporate faster than colder water, but it won't suck your tank dry. I lose about a gallon of water a day in my reef tank, that has powerful
PC lights and no top on it. It's just a matter of topping it off. If that is the case though, and you are losing alot of water, you are also probably heating up your water quite a lot. When you put stong lights on your tank like that, you have to make sure you have adequate air circulation as well.
