Red Sea Reefer Sump Overflow Downpipe (250/350/450) (R42220)

The Red Sea Reefer Sump Overflow 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 Overflow Downpipe is used to connect to the Aquarium Overflow Downpipe from the Weir Section, and provides a secondary port for carrying water if the Weir Section overfills.
