Hey Jay! so we need to rationalize what you have with what you should get, ro unit- anything is better than tap, you can put a T fitting on the output side, one line to drink and one line to a di unit, a di unit is available as an add on for about $50. Lighting, forget the MH for now and concentrate on lower light corals, leathers,mushrooms,colts etc, avoid the high light demanding ones, clams,anem's sps etc. The canister filter can be used with the thinking"I must clean it weekly" if not problems will arise.Sump, you can go with or without, if your on top of your waterchanges and cleaning your fine.Post pics of the skimmer working and we will help you fine tune it, good luck.
