Why do you use metal halide even if the tank is not planted? Metal halides certainly can give off a lot of heat. Perhaps switch to fluorescent lighting?

I like the intesity of the light, Fluorescent looks stall and static to me. All personal preference I guess.

I would be concerned about that much heat in your hood. Is it wooden? How far are your MH's from the glass? I use 3/32" glass with my 175W MH's and the glass never gets that hot, I've got about 2-3" clearance between the glass and bulb.

The tank is built into the wall, There are fans that ciruclate heat out the back into a utility room. The cabinet doesn't get hot just the glass. The lights are 150w but only about a 1/2" clearance. There isn't enough room to pull them up any higher. They're pendant lights and the bulb is another 4 inches up in the pendant but all the heat is directed down to the glass with that small amount of space to escape. I only use the the canopys to cut down on evaporation. I may just pull them all together now.

thats bizarre that it would break in half like that... ive accidentally dropped my glass tops in a few times while moving stuff. scares me every time. btw joeyballz... what kind of sd's are those... i saw a few the other day at a lfs and was wondering if they maybe lost there spots as they got bigger? how big are your?

Not sure what type they are, I bought them from a girl on Craigslist. The biggests are 4" and the smallest are 3"
