Fluval SEA PS2 Mini Protein Skimmer for Marine Aquariums, Treats up to 20 gallons

Compact, yet powerful, the Fluval Mini Protein Skimmer helps to remove dissolved organic compounds and other harmful substances from your aquarium before they have a chance to break down into dangerous nitrogenous waste, which can be harmful to aquarium inhabitants.

The skimmer's large reaction chamber allows the air and water to mix effectively to efficiently strip the organic waste from water molecules, while its unique 32 needle-wheel impeller is designed to produce the optimal bubble size for maximum protein collection.
