Collection: Red Sea Protein Skimmers

Red Sea's Reefer DC skimmers are listed in three sizes: the 300, the 600 and the 900. Alongside each is an upgrade kit carrying the same size number, sold separately, which converts an earlier regular Reefer skimmer of that size to the DC version rather than replacing the whole unit. Those numbers follow Red Sea's own naming for the Reefer range rather than a tank capacity, so match them against the Reefer system the skimmer is going into instead of reading them as gallons or litres. Upgrade kits are tied to one size and are not shared across the three, so identify which skimmer you already have before ordering one.
