Science & Engineering Perfection

The main theory behind creating a successful protein skimmer is maximizing the exposure of air to water. The most effective way to accomplish this is having a massive quantity of the smallest bubbles exposed to water in the perfect ration.

Organics have a very specific structure which makes them polar (meaning one end is very different from the other). As it turns out, one end is also very “hydrophobic,” meaning it is repelled by water, and attracted to air. Using this biochemical feature, we can infuse water with air and attract these objects. Using the same principle as lathery soap, the bubbles will attract undesirable organics,  rise to the collection cup, removing them from the aquarium.  

Next Generation Technology

The MRC Pro Series of professional grade protein skimmers features the heavy duty construction you’ve come to expect from MRC: 100% cast acrylic, Spears plumbing, 100% American made. The Pro Series is powered by a new and improved needle-wheel and the exclusive MRC air aspirator, providing the performance and quality one would expect from the industry leader.


Up to 2,000 Gallons | Ozone compatible | High Quality 3/8″ Cell Cast Acrylic & 1/4″ Cell Cast Acrylic tube | Needle-wheel technology *Shown with optional MRC triple-cone washdown system* The MRC Orca Pro III is the flagship model in the MRC Pro Series line of protein skimmers. It is everything you’d expect from a top-of-the-line skimmer. It’s powered by a custom 1/3 HP American made pump with our high-power Needle-wheel technology and the exclusive MRC air aspirator. It features a massive 12″ reaction chamber body for unparalleled reaction time & performance. The base is constructed out of 3/8″ cast acrylic; all tube is 1/4″ cast acrylic. All plumbing parts are heavy duty Spears plumbing. The Pro III is the public aquarium sweetheart, allowing them to remove larger, less efficient, and less effective skimmers. The Pro III is a fish and SPS lover’s dream come true. If you love a heavy bio load or need pristine waters for your SPS, this skimmer is for you. The MRC Pro Series sets a new standard for quality and performance.
