Aquarium maintenance doesn’t have to be an overburdening chore. Let MRC life support equipment do the dirty work while you enjoy the view.


Up to 1,450 Gallons | Ozone compatible | High Quality 3/8″ Cell Cast Acrylic & 1/4″ Cell Cast Acrylic tube 

+Series Recirculating Protein Skimmers provide the perfect upgrade for finer control and higher efficiency. Utilizing the two injector assemblies and longer dwell times, high bio-load systems don’t stand a chance. The recirculating design allows for a precise turnover rate, tuned to the demands of your aquarium. Instead of the traditional single pass, a particular body of water is processed multiple times before exiting the skimmer, increasing production and efficiency.  Utilized by professional aquarists and organizations worldwide.
