So for my 55 gallon tank the lighting was still not very bright even I just upgraded with new lights this past week. It has the two aqueon deluxe hoods. With those two hoods I don't get very much light. I decided I would do a mod to get a lot more light. I lifted up the hood and found under each one is a 15 inch bulb. On each side of the bulb is a small little open area. I thought to myself..... Hey! A cfl bulb could maybe fit there! If I did that I would be able to use four bulbs. So I looked around at what I had at home to wire it all up. Sure enough I had everything. It took a few hours but the tank now looks amazing!! I'll get some before and after pictures tonight. Right now there is too much glare on the tank.
