The most recent addition to Adaptive Reef's offering of reefing equipment is a line of DC-powered protein skimmers that deliver on multiple levels including convenience, quality construction, and versatility. There are two models available that can accommodate tanks anywhere from 90 to 300+ gallons thanks to the interchangeable neck inserts and adjustable Sicce pump. The included acrylic neck inserts allow you to adjust the diameter of the skimmer's neck based on the level of nutrients in your aquarium. Combined with the ability to adjust the flow using the controllable Sicce SDC skimmer pump, you can achieve optimal nutrient export no matter what your bioload looks likes. The included air flow meter with a valve allows you to further fine-tune the skimmer's performance by regulating the amount of air going into the pump.  

In addition to this impressive versatility, Adaptive Reef spared no expense when it comes to the quality of construction and materials. The skimmer body is made using a combination of PVC and acrylic and is assembled using titanium screws that won't rust or corrode in harsh marine environments. There is an included air silencer to reduce operational noise along with silicone feet to help reduce the transfer of vibrations.

Sicce's SDC pump is equally impressive with its own set of features that further enhance the protein skimmer's performance including 5 preset flow modes and an internal thermometer. The SDC pump is also Apex-Ready making it one of only a handful of protein skimmers that can be directly monitored and controlled using a Neptune Systems Aquarium Controller.
