The lights.
I just made a simple box to retrofit lights I already had. Dual 400 watt Metal Halide and 2 - 24 watt Actinic T5's.
Overkill for a shallow tank but so far so good. I love them and my corals really seem to be happier than ever. I am running the 14K bulbs 8 hours a day and Pure Actinics 12.
Originally I hung the fixture from the ceiling but I felt uneasy because it is a bit heavy and the ceiling is concrete. Getting a good anchor in it was hard. Oh and ceilings are 14' tall in my place so the cables were really long and just didn't look right.
I rigged up a way to use the fixture I built though in a unique way. I will post pics soon of how I did it. I absolutely did not want a canopy this time.
Anyone have any ideas for reflectors to replace those ones? It would need to be something that has the same footprint to fit where those ones are. They are not great and I want to chnage them eventually.
