Full Details

The Cobalt Aquatics MJ series of pumps is the same Italian-made MJ you have been using for the last 20 years. Reliability and low operating noise have been the staple of this pump series, a principle reason why aquarists around the world have been using them for decades. After the original MJ distributor moved operations to China, Cobalt Aquatics jumped on the opportunity to work with the Italian manufacturer to continue to provide a source for this high quality product line. Mostly used for wave makers, protein skimmers, calcium reactors, nano aquariums, under gravel filters and hydroponic applications.

  • Quiet By Robert on 3/9/2014

    The maxi-jet double pack prefilter fits on it, its about as quiet as my heater haha, i sleep close to it and can never hear it
  • Serviceable, quiet powerhead By Jeff on 5/2/2013

    I bought this powerhead for extra flow in my 18" cube coral quarantine tank. It has nearly silent operation and does its job well. I would encourage anyone looking for a small, inexpensive powerhead to give this product a try.
  • Nice pump By bruce on 4/13/2013

    The Mj400 is powering my ATO. I was very surprised how quiet the pump ran and would definitely recommend.
