I have a 40 gallon breeder I'm planning on setting up as a frag/grow-out tank, my question is, does it have to have a sump and skimmer?? Or will just a power head and water change work? I was initially going to do sump/skimmer, but I don't have the tank drilled nor overflow installed yet and wanted to go ahead and set it up if I could without those things. Please advise....
