So last night I was just sitting in my living room when I heard a horrendous noise.. Look over and the glass that covered the top of my tank cracked then fell in the water. it has to be because of my light. I have a metal halide, but pretty sure it's a home made fixture, so it has no ends on it or cover over the lights. I had someone build for me some ends to keep the light in, after installing them to the light last night and having my light on for only 1 hour, compared to it could handle it before without the ends for around 8 hrs.. I've already been having problems with the amount of heat its been letting off into my tank but the glass definatly kept a lot of that out. Was wondering what others do who have a light like this? Would it work to put a clip on fan somewhere up there? Or would this even do anything? But now that there is no glass up there today when i turn my light on it can make my tank temp jump 10 o! Which isn't good. Any advise?
how do i keep my metal halide rays down

DE metal halide need a glass shield. SE do not need one. Any glass used around a MH that is going to get super heated needs to be tempered.

you can buy halide housings/reflectors/housings that accept a fan to help move the hot air out of the light before it makes its way to your tank.
Other option is a clip on fan on the top of your tank blowing across the water surface to drop the temp (usually good for a 2-3 degree drop) - only problem with this solution is the evaporation will greatly increase so you will need to keep up on your ATO replenishment.
