the glass top not only deals with the lighting but your PH also. A glass cover will hinder gas exchange at the surface and cause a lower and unstable PH. This is the reason for not using glass hoods.

so mabey i should buy the hanging kit and hang it higher up. mabey like 6" but then again i dont what to hang it too high and loose the good light at that bottom of the tank either. now for the 150w vs 250w. i have my fish tank in my room, my grand parent wont let me have it any where else lol. and i tink the 250w would make my room brighter then the light post out side my room. and people driving by might think i am growing stuff in here at night lol. not to mention i also have a computer on the same circut. would this pose any problems?

The 250w is going to produce even more heat obviously. FWIW I have 2x250w MH 10" over my 55 gal w/ 20 gal sump, two fans mounted in the canopy and if room temp hits 82+ deg. I have heat issues. My tank will easily hit 86 deg. on a day like that. It runs at 82 deg. with just the heat from the lights, no heaters on. MH get extremely hot.
and should i run a new 15amp 120volt GFCI recp?
It may be a good idea depending on how much other equpment your using . If you don't already have a GFCI I would strongly suggest using one.

well i do know that the light does also have fans mounted in the fixture it self. and i am thinking about getting 250 and mabey raise it 1' to try to cut down on the heat issue. 1 day i want to get a 90g tall hexogon tank and a 250 might be perfect for it. lol and yes i do i have a GFCI recp.
