Hey everyone, I've decided to convert an extra marineland system 12 into a saltwater aquarium, and though I was originally only planning on having FOWLR, I was wondering if there were any corals that would grow under really low light. We're talking a 13W 50/50 10,000K/Actinic compact fluorescent and a small LED moonlight I'm going to fix on the top. I know that isn't much more that 1W per gallon, but I think that number may be misleading, as the depth of the tank is only 17in. So I figured I might be able to get away with a few mushrooms or maybe even polyps. The flow isn't great but I may shell out the money for a small powerhead, if that would indeed help. What do you guys think? I don't have any experience with saltwater other than the decent amount of research I've done lately. Any specific breed suggestions would be nice, although I'm pretty much limited to Petco and a local fish store. Thanks guys!
