Used Neptune Systems DOS Used

This item includes one (1) used Neptune DOS.(two are pictured, but only one included with each item paid for). Two of the ports are the John Guest style push connect adapters and two are what the DOS usually comes with. No tubing is included with this item. Just the pump, power supply, and an AquaBus cable.   Some of the pump heads have almost no use and others are well worn, so it may be wise to pick up a spare or two which we also sell here.   For all "USED" and or "CLEARANCE" dry goods all sales are final. Please read the description thoroughly.  No returns, refunds, cancellations, or exchanges will be issued. All Sales are Final.
