Red Sea Lids

A Red Sea REEFER without a lid loses fish and loses water, and the water is the part that costs you. Evaporation is what moves salinity overnight and what keeps the top-off cycling.

These are Kraken Reef lids cut for the REEFER rim rather than trimmed to fit it. The mesh sits in a frame made for that exact model, so it clears the overflow box, the return and the light mount instead of being cut around them with a knife.

Read the model name on your tank before ordering, including the generation. Red Sea has revised the REEFER line more than once, and a lid for an older-generation XL 425 is not the lid for a current one. The listings name the generation because the difference is real and it is not visible from a photograph.

If your tank is a Waterbox or a Reef Casa, those fitments are on the Kraken Lids page instead.

Not sure which row is your tank? The Lid Finder lists every Red Sea, Waterbox and Reef Casa model next to the lid cut for it.
