Reefer RSK 300 Protein Skimmer

Notify me when this product is available:

RedSea's high-performance REEF-SPEC® Skimmers feature a combination of PSK pumps with proportionally sized venturi, bubble diffusor and reaction body that optimizes air-water contact time for steady waste removal.

Designed with hobbyists needs in mind, the REEFER™ Skimmer is whisper quiet thanks to rubber connectors which dampen the vibrations as well as a robust air silencer. With features like the FoamView™ window, built-in neck cleaner and extra-long valved waste tube, we guarantee an enhanced home reef filtration experience.


  • Ergonomic diffusion chamber evenly disperses the fine bubbles created by the PSK pump across the skimmer cone, without reducing air or water flow.
  • Quiet operation, with vibration absorbing components and a large air intake silencer.
  • 3 assembly options for ?exible positioning of the pump inlet and regulation valve, according to your sump.
  • FoamView™ window in the collection cup to easily monitor and adjust the foam height.
  • Built-in manual neck cleaner.
