I just put this above my 300 because 1 thing acrylic has going for it is the clean look. It is 4 48" 32w T8 bulbs (6000k). They are about 5" above the tank, and I was wondering what your opinions are about raising it, lowering it, or leaving it alone. Thanks for looking!
I don't think thats enough lighting. 128 watts on a 300 gallon is gonna be really dim. You should consider t5 and metal halides with vho/power compact, vho, or just power compact.
