I've calculated that I have 2.8 watts per gallon in my new tank, it's 18 inches deep and I was just wondering what corals I could keep in this? And if it's worth maybe getting an additional LED strip for it.
I think that's what I had. If so, you should be able to have corals up to some lps like acans and softies like mushrooms and xenia. You can't high light corals though. Do you know what brand the light is?
