I think that you shouldn't have too much heating issues if you are able to raise this light 6-8in off the surface and use the fan. You can even go higher if you're able to (talk about a bright desk light) 10-14in, but you, of course aren't going to get the same intensity as closer, but with that much light over such a small tank it should be fine... as for the glass on the tank, i don't really agree with this, sorry Cody. Closing the top will not allow for oxygen exchange to occur and it'll mess with your PH.

I have kind of a silly question. I've read you can damage your eyes with MH lights. could this hapen since its on my desk? or do have to acually stare into the light?

Plenty of tanks have glass tops. This is vital in small reefs with a lot of lighting to make sure evap doesn't get out of control. The main issue I see in having a glass top is that it blocks light somewhat. I have one on my reef, and no complaints from me. No jumping fish, no thing bad falling in the water, etc. I have plenty of oxygen as well because my powerheads are directly at the surface, and my pH stays at 8.1-8.4 (tested at different times of day).

As to the question, I have no idea.

Staring directly into the sun will damage your eyes, but the light that it emmitts doesn't harm you. same goes for a MH, If you are staring into a 400w MH then yes, it'll hurt and you'll see poorly for a long while and it could even damage them, but the ambient light given off shouldn't cause any harm like the sun.

To each his own, I personally don't use a cover.

Well to kinda join the side conversation, I personally don't use lids on my larger tanks, like my 600g main display tank

not only is it pretty costly for not that much benefits, it blocks light and doesn't let me get into the tank when I need to

On my 24 gallon tank though, I do use a glass lid and besides having to clean salt creep off of it every now and then, it hasn't seemed to harm anything...

so I'm cool both ways lol
