With Metal Halides I wouldn't use any cover. You could have a heating issue if you do. Just my opinion. :D

Well I had a brain fart :rolleyes:. What about using the glass and just measure the lights I will see what I can do on a pic.
I hope this helps I tried to describe it best I could I think you should get it.
for the heating reverse the fans to pull instead of push it would suck the heat off the top of the water and push it away from the tank. I think I had a pretty good brain fart lol :rolleyes: .

Whats a benifit of not having a top on the tank with MH other than keeping temps down? I have a top on my tank and it seems to keep the temp more stable, usualy never changes more than +/- 1 degree and I also barley loose any water to evaporation

But what about my idea? would it work? it would still have evaporation but not as mutch like the egg crates and it wouldnt have any light distortion cause the lights would be completely open.

It would function but cutting the glass to size I wouldn't think would be the easiest. Plus evaporation is a good thing, it allows heat to escape and it aides in the addition of kalk if you want to.

but I also added to revers the fanse so they pull and not push. If they pull then it would suck the heat out of the tank.

It's more efficient to cool the water and since cooler air is denser you will push more cfm of air by pulling air in, at least in theory.
