Sump or no sump?

I put my HQI 150MH over my 20H and in one day it raised 9 degree's to 89... took it off and replaced it with a 4 bulb t5 fixture and it only raises 2 degree's. look into 4 bulb t5 fixtures, you can get a fish need it for $80 before shipping and you can keep what ever your heart desires
