Potent and Efficient

Why spend all your time cleaning your aquarium when your equipment can do the dirty work instead? Sit back and let MRC +Series skimmers do the heavy lifting as they have been for two decades.

Happy Livestock

Give your fish and corals the environment they deserve: clean and fully oxygenated. The MRC® Signature Series can help you with that.

We Expand with Your Success

Our  injection line is the only upgradeable protein skimmer in the world. Instead of having to throw out your skimmer every time you upgrade or add to your bio-load, with MRC®, you simply install upgrade parts, reducing waste, monetary loss, and time. Available for aquariums up to 8,500 gallons.

Overview

Up to 500 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-3 provides increased dwell times in the same footprint of the MR-2.  Also equipped with a port for an optional second injector assembly.
