MRC® MR-1™ Protein Skimmer
Overview

Up to 175 Gallons | Ozone compatible | High Quality 3/8″ Cell Cast Acrylic & 1/4″ Cell Cast Acrylic tube 

+Series Signature Protein Skimmers have been successfully running aquariums for two decades. Our injector assembly uses a pressure differential to generate a massive quantity and quality of bubbles to maximize protein skimming. Historically, these have been powered by high pressure (high power) pumps, but with the advent of ultra efficient DC powered pumps, these skimmers are more potent and efficient than ever.

Utilized by professional aquarists and organizations worldwide, the MR-1 is the perfect solution for smaller systems. Don’t be fooled by the tiny footprint; it’s every bit as powerful as its big brothers.
