I have a drilled 55g tank. With refuguim. Do i really need to use a skimmer. I heard people not using a skimmer when they have a refuguim. I wanted to know. If I dont need one that will be good. Because I can use the money on corals or fish. I just setting up my tank. I have cured live rock already. I cured it in a rubber maid bucket. So die off will not be a issue
