Bio-Sump™
All skimmers operate off the same basic principle and theory: mixing water with air. The differentiation occurs when evaluating who can do this best. That is where MRC® comes out ahead. We have several different skimmer designs, using different technologies for different setups. From our MRC® Pro series, uses ultra efficient pumps, our amazing needlewheel design, and our ingenious MRC® air aspirator: these filters have been tried, tested, evaluated, and honed to perfectly and ideally create an interface of bubbles and water, by maximizing bubble surface area, dwell time, and maximizing skimming ability. It simply cannot get any better!

Simple
Installation has never been easier. Fill, plug, and play. Choose your preferred media then plumb in-line with your current system or use our ECO 132 pump.
Capacity
Between 1430ml & 2740ml the xSeries Reactors are ready for just about any media you could possible throw at them.
Precision
All xSeries Reactors are precisions made with the highest tolerances. We like things to be right and right the first time around.
Detail
We’re a bit obsessive at MRC®. We not only made our tubing match, but it’s also food grade and 100% American made.
