Ok, so if I go with a canopy, I will obviously go with Sean and others recommendation. After long searches, my alternative would be this fixture to keep my top open. This fixture seems to have great reviews and has pretty much everything included. It is the 250x2 with T-5 actinics for 716 total watts over my 75g. What do ya'll think?
