Be confident in your purchase we're an Authorized Simplicity Dealer. How cool is that?!?!? Get power, precision and control with Simplicity DC Skimmers. Our DC Skimmers use an adjustable DC pump and needle wheel, regarded as one of the best methods to shred air and water in order to create micro-fine bubbles. The long contact time between the water and the air that our skimmers provide is key to successful protein skimming. The bubble plate, wedge pipe indicator, air intake adjustment and controllable pump allow you to achieve the best performance for your unique system.
