Im not set on 6 lamps, its just that most of the 8 lamp fixtures i've com across will be to wide for the 75gal. I just figured that the bulbs hanging over the rim would pretty much be a waste. As far as the fans go im just indifferent to them. If the fixture has them great if not oh well. It just seems that the fixtures im interested in with fans seem to be priced out of my range like the ATI. Im not however opposed to the TEK Elite which does have fans and better reflectors and its really only an extra $100.
Both of the aquactinics fixtures i was looking at have fans but they are pretty old and I figures it would just get harder and harder to find the parts if needed. Do you have any other fixtures that might be of interest to me.
