Tank cover or not

[BCOrchidGuy]

CW, for what it's worth, I don't like covers, I find they trap alot of heat, and they get dirty really quick. It doesn't take much at all to get them covered in crud, that surely must reduce the amount of light that gets through to the tank. I believe the benifit of the cover is to slow evaporation and to keep things from falling in. I take care of evaporation with an auto fresh water top off. I learned along time ago, don't put stuff over an aquarium if you don't want it to go in (other than lights WHICH are always secured of course).
Anyway that's my two cents worth.
