Aqua Euro USA Protein SkimmerOur Aqua Euro USA Protein Skimmer maintains a clean marine aquarium ecosystem by effectively eliminating dissolved organic compounds (DOC), which is a must for keeping a pure, healthy environment for your aquarium inhabitants. This protein skimmer is made with high quality thick acrylic (not plastic) construction and the bubble plate diffuser increases 'skimmate'. Increased skimming ability makes this protein skimmer ultra efficient; chops water and air into a fine mixture of micro bubbles and the high bubble dwell time results in large collection of DOC. Aqua Euro USA's Protein Skimmers are highly favored among aquarists due to their superior craftsmanship, body design, performance and affordability.
