Which power heads would you recommend? I plan on going with three powerheads hooked up to a naturalwave pump timer. I was originally planning to go with a canopy but I'm not sure how it would fit the tank. I'm going to be getting the 30" coralife lunar display, which has 1 full spectrum bulb, 1 actinic bulb, and 1 bulb with lunar LEDs, and has 3 cords and switches for them. I'm putting those on a timer too. The tank I have is made by All Glass Aquarium, they have a canopy for it but I was not sure if it would fit with the coralife fixture.
