Maxspect Jump MJ-SK400 is an in-sump protein skimmer for saltwater aquariums. The adjustable DC pump and dual needle wheel design produce fine bubbles that collect organic waste into the skimmer cup.

Adjustable skimming

The front control dial allows you to fine-tune the internal water level of the skimmer. An integrated silencer and bubble trap keep the unit clean and reduce intake noise and microbubbles returning to the sump.

The compact design helps fit the skimmer into limited filtration spaces. The controller features a feed mode, start delay, and overflow sensor for the collection cup.

Control for daily maintenance

The start delay is useful when the sump water level stabilizes after other equipment has started. Clean the cup, neck, pump, and air intake regularly to ensure consistent skimming performance.

Manufacturer sizing based on load

Technical specifications

Choose based on the load caused by the fish population and feeding. Ensure there is enough space above the skimmer to remove the collection cup.
