Hey guys, I'm moving into a new house within the month and currently have a deal for a 75g complete system minus a sump. The pump I'm getting with the tank is a 700gph marineland. I'm looking for a good sized sump to complete the system so it's operational once I move in to my new house. Not looking to break the bank, since its my first experience going with a sump. Anyone have an old unit kicking around?
