I am looking into building a sump system for my tank, I have no problem building it but I dont know how, I know how to build the overflow and pump back to the main tank. but I dont know what to put into the sump itself, I was going to use a 20 long tank as the sump for my 40, :help: but what do I put into the sump for it to work properly, I would also like to install or build a skimmer in it as well.
