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.

  • Fully sealed intake for internal and external use
  • Universal intake tube Adjustable hanger with cord guide and 6 Ft power cord
  • Adjustable venturi with silencer

  • Nice pump By Tudi on 8/22/2013

    Pump its quiet, powerfull and its wort avery panny
  • Excellent, quiet but powerful pump. By Joseph on 3/8/2012

    Vastly superior in every way to the now cheaply made MaxiJet brand. Get the Cobalt, you won't be sorry. I use one for my mixing bucket, another to run my reactor and UV and keep another in reserve. You can't have enough of these - and they come with everything you need to convert it for a variety of uses.
