You small time ghetto tank builders. For a hood I have the VHO hang sitting on top of the tank. I have my MH pendant hanging from a bathroom shelf with 2 of the shelves removed so there is room for the light. The hood itself is a piece of metal that was for my jeep bikini top that is 4ft long and to that I have a white towel clothes pinned to block the light. I have 2 refugiums tied to it, a 5 ga bucket with a hose coming out to a float valve for top off and a 30 ga garbage can with a pump and another float valve on the other end. I put my aqua C remora on the sump just sitting over the top of it and my tank is acrylic and 20 years old. Its so scratched I don't know if its crystalizing or not! Where is my camera, time to roast this beeeaaahtch!
