Kinda unsure about this. I have a 10gal, 20inch wide tank. I currently have the Aqueon hood that fits 2 6inch incandescent bulbs, that I replaced with two 20watt 6500k fluorescent, but they barely fit in there and theyre melting the top plastic part.
I know theres the Aqueon deluxe hood where you can but a single 18inch tube light, but the tube lights that size I usually see are only about 15watts. I feel like I'd want more than just that for my 10gal, even if my plants are low-med.
Just wondering what people use...
