Also remember that the OP wants to use his original hood, so most fixtures will loose light unless they're pretty skinny. I tried adding a t5 to the original hoods before and you lose a lot of light, that's why I suggested the led strips mounted inside the original fixture, and I didn't mean just the normal TrueLumen led strips, was just suggesting the brand, I should have specified
The glass spot for my 20g is wide enough to fit the Finnex over it. I can only assume that the hood for the 36" BF is the same if not bigger.
