My Reef Creations Orca Pro III Protein Skimmer

The MRC Orca Pro III is the flagship of the MRC Pro Series—engineered for the most demanding reef systems, public aquariums, and SPS-dominated displays. Designed for unmatched performance, the Pro III features a massive 12" reaction chamber, heavy-duty construction, and a custom 1/3 HP American-made needle-wheel pump that delivers exceptional air draw and contact time.

Constructed from 3/8" cell-cast acrylic with 1/4" acrylic tubing and premium Spears plumbing, this skimmer is built to endure years of continuous operation. The optional triple-cone washdown system (shown in photos) further boosts efficiency by reducing maintenance requirements.

If your system demands extreme nutrient export, superior water clarity, and industrial-grade reliability, the Orca Pro III stands in a class of its own.
