From 300 gallons to 1,800 gallons, the +Series Recirculating skimmers are ready for just about any system you could possibly throw at them.
Precision
All +Series Recirculating skimmers are precision fabricated to the highest tolerances. We like things to be right and right the first time.

Overview
Up to 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.
