Why does BRS recommend this?

The Cobalt MJ line of pumps is great for auto top off systems, reactors, or low flow equipment.  These pumps are made in Italy and are much quieter in operation than similar pumps that appear to be identical.  With so many applications the Cobalt MJ pumps have some of the best value for a submersible pump. 

  • Flow Rate: 106 GPH
  • Maximum Head Pressure: 29"
  • Power Usage: 5 Watts
  • 3 Year Warranty
  • 3/4" Input
  • 1/2" Output

 

Dimensions - 6" x 3" x 2"

 

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 rotational output
  • 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
