Do you want a hanging fixture or leg mounts? Keep in mind there is a lot of things that can effect your access to the inside of your tank and do you want to run an open top. Personally I had a fish jump on the floor aka carpet surfing. If you get attached to a fish and hate beating yourself up over a personal mistake. Tight glass lid. I am guessing your hood has a plastic front to open. Then an acrylic space for your fixture now. Then spots perforated to pop plastic for equipment to fit in and you are just looking for a fixture to lay on top of the acrylic part and be done with it and you want to spend between $100-200?
