Red Sea Reefer Skimmers are powered by Sicce`s PSK Skimmer Pumps, a pump well known among hobbyists around the world for their efficient output.


The silent operation of the Reef Skimmers are attributed to the large air intake silencer, and the vibration dampening feet and connections.


The diffusion chamber of the Reefer Skimmers disperses microbubbles produced by the PSK skimmer pump evenly through the conical ergonomic body, while maintaining air and water flow.
