  • DC Powered with Smart Control
    • Overflow protection
    • Feed mode
    • Start delay

  • Small footprint (7.5" x 7.5")
  • Ideal for tanks 100-265 gallons

Patented Dual Needle Wheel Design

The JUMP Skimmer incorporates Maxspect`s unique patented dual needle wheel technology, which features a spinning needle wheel and a stationary one. This combination produces much finer, more concentrated bubbles for more efficient waste removal.

DC Powered Skimmer with Smart Control

The SK400 is DC powered with a fully adjustable flow rate. The included controller is loaded with features such as feeding mode, overflow protection, start delay and more!

Innovative Designs -- Not Your Typical Skimmer

The MJ-SK400 features a pipe-less design and a compact footprint, saving precious real estate inside your sump.

The float switch is built into the lid and is triggered when the collection cup becomes too full. The skimmer will automatically shut off when water levels are too high, thus preventing waste from overflowing into your sump and back into your system. Once the float switch returns to its normal position, the pump will resume operation after a few seconds.

The air silencer has been ingeniously integrated into the bottom panel of the skimmer, where the sound is further insulated by the water around it.

A special integrated bubble trap prevents annoying microbubbles from escaping into your sump, and a bowl-shaped bubble diffuser reduces turbulence to direct air upward instead of outward so that bubbles and dissolved organics rise easily through the body up into the collection cup.

The skimmer can be easily disassembled for cleaning and maintenance-- just loosen the thumbscrews in each corners to easily remove the entire skimmer body.

Can this product be used in Japan? Also, please tell me the shape of the plug.
Asked : Oct 30, 2020
I do not believe this can be used in Japan as it has a standard 120 V plug for use in the U.S.
Answered : Oct 30, 2020
What is the input voltage range for the pump? Does it support 220 volt as well?

This skimmer is for use with standard 120 V in the U.S.. I don't believe it will work with 220 V.
