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.
