glass on tank

[oceangrl11]

Hey there everyone.
How necessary is it to keep the glass pieces on top of your aquarium? i do not have a light yet but the glass gets all cloudy with the salt deposits and I think it would look better to have it off. What do you think? Any info would be awesome.

you can take it off, it will provide better gas exchange in the tank, which is a good thing. you will evaporate more water with it off,. but its not required to have it on.. alot of people run without them, including myself
