ok as many know i bought the 180gallon online and i was wondering and wanted your input on either a internal or external return pump and what brand i want something thats doesnt consume up alot of electric and that doesnt put out alot of heat and i was thinking about going with a 75 gallon sump im planning on just doing it a fowlr for now and maybe later on down the line a reef so i want to know your input on how i should go about setting it up thanks
