I have a 54 gallon corner (fairly deep) tank. It's been going for about a year, and generally successful with mushrooms, polyps and leathers. It has two regular 20w 50/50 flourescents. The fixture sits directly atop the glass tank cover.
Is there a simple upgrade in lighting that I could make, without getting into fans, chillers, elevating the light fixture, etc.?
I gather that the best possibility might be VHO
, but I don't know how many bulbs, wattage, etc. From what I understand, VHO
runs cooler than PCs and T-5. Also, I had read somewhere that there is something call HO
, though maybe that's been obsoleted.
I would appreciate your thoughts. As I said, the corals have done OK, not great, with what I have. But I don't want to get into multiple levels of complexity or cost. I would be happy if there's something simple that would be a moderate upgrade.
