  • Reliable very adaptable strong flow rate By on 10/12/2017

    All around solid pump from Cobalt. I use it for ATO. Very reliable.
  • Works right By on 5/22/2016

    I am using two of these, one on a carbon reactor and the other is feeding my cpr hang on the back refugium.
  • Quiet By 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 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 on 4/13/2013

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