Red Sea Reefer Sump Valved Downpipe (250/350/450) (R42217)

The Red Sea Reefer Sump Valved Downpipe (for the Reefer 250, Reefer 350 and Reefer 450) is used within the Red Sea Reefer Aquariums in the Sump section, and is part of the recirculation system that moves water from the main display, into the sump and then back again. The Red Sea Reefer Sump Valved Downpipe is also used to control and adjust the flow of water from the Sump Return Pump, which then in turn adjusts the water level within the Weir section and therefore the height of the water in the Aquarium itself.
