MRC Orca Pro III

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 Baldor with our high-power Needle-wheel and the exclusive MRC air aspirator. It features a massive 12" reaction chamber body for unparalleled reaction time & performance. The box 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 was challenged by a system with 2,000 fish; the Pro III took the challenge and destroyed it with ease! 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.
