Hey guys, I am trying to get started with my first reef. I am going to wait a couple of months to finish up any research I have to do and let my tank mature a bit more. I have a 40g tank. I have a canister filter, a regular filter, a current maker, and I ordered my skimmer today (which is supposed to come in a week.) my tank is 3 months old, I'm happy with it. But I think it can do better. I want to buy a HO
T5 fluorescent light, but I don't know how many watts or I have no clue.... The length would be 36". Should I get a 78 watts or 156 watts? Or how many watts? I want to have pretty corals, not that many fish. Another quick question, should I have my skimmer as a hang in or a slum?
