The Maxspect Jump SK400 is an excellent and affordable option for efficient protein skimming in reef aquariums from 100-265 gallons. It features a patented dual water inlet with dual needle wheel design. Water is sucked in from both sides of the skimmer into the dual needle wheels to create even smaller, higher density bubbles, which results in increased surface area for removing organics from your system. The Jump Protein Skimmer is also equipped with an overflow sensor in its collection cup, which will turn off the skimmer pump when triggered to prevent any accidents. Once the float sensor is back to its normal position, the pump will automatically resume power after a ten second delay. The included controller can be used to easily adjust the pump speed or to enter a "Feed Mode" which will pause the skimmer for 600 seconds during meal times.
