I am considering upgrading my 20 gallon FOWLR tank to a 55. I am wanting input on the best setup for a sump. Basically im thinking of using my 20 tall for the sump and looking at a reef octopus skimmer. other then that im really in the dark as far as where the compartments should go, what biomedia i should use, and whether to to an overflow box or just drill it. Any sugestions would be greatly appreciated. Thanks in advance
