Then raise the light or leave it? Good lord. Thanks for all the light picture's. It helped
huge with my decision. Depending on what you guys think I may order the covers with
new bulbs. I keep tossing the idea around and around. Not sure of the benifits of removing the glass. That and worried about the evaporation.....help!
Thanks any help would be great!

Removing glass cover from your tank would be a good idea just for proper gas exchange; someone just lost all the fish not too long ago on here (Alfredshouse?) because of lack of O2. Our tanks are not perfectly designed for proper gas exchange anyway.
Ideally tank height needs to be equal to its width, or greater like a lake or an ocean, but this is the case only with cubes, so we all need some help with gas exchange.

Re T5, I don’t use any cover and my 6 lamps Tek fixture is on the legs at the lowest setting which is about 6” or lower from water surface just above the splash level
