  • So quiet By Josh on 12/15/2014

    it is soooo quiet
  • Love these pumps. By Despairodyne on 11/26/2014

    I have about 6 of these atm and use them for transferring salt water and ro/di water from containers to tanks and to stir my salt making bucket.

    If the Sicce pump I bought for my Nuvo 16 isn't quiet enough, I'm going to split the returns and use the smaller Cobalt MJ's.

    Well worth the price.
  • beware leaking voltage By jonathan on 9/27/2014

    i had this pump running for 7 months feeding a reactor on my 75g, when i started having coral die. i tested and found it was leaking 110v into my tank!!!

    i lost a bunch of sps and ricordia thanks to this pump...

    use at your own risk....

    i bought a dc pump to feed my return, reactor, and skimmer. months later i once again have sps and ricordia thriving. this pump cost me a bunch of beautiful coral and money.
  • Super quiet! By perry on 7/22/2014

    the pump is one of the quiet things i have running on my system. I use it to run water throughout my UV sterilizer and it returns the water to the tank with no problem.
  • Really quiet, really powerful By Adam on 6/4/2014

    I've only had the MJ1200 for a couple of days, but so far I'm really impressed. I see more in my future.
  • Great power head, good pump By Devon on 5/19/2014

    I got this MJ1200 to use with the BRS canister reactor with carbon. It works very well and is the quietest pump I own.

    I also tried using it as a sump return because I wanted to reduce the return pump noise, but the flow rate drops to 50% with only 2 foot head pressure.

    I may end up using two as returns because they would still be quieter than one mag drive 3.
  • Good pump By Benjamin on 4/10/2014

    I recently replaced the two other mj1200's with these a few weeks back and the difference is ridiculous! These guys are completely silent!
  • Just quit By Bryan on 3/7/2014

    This unit was purchased with a BRS Reactor. After three months the pump just quit.
  • So quiet ! By Vince on 1/14/2014

    Swapped out my AIO sump pump with this, I can sleep at night!!! This is better than the MJ by a mile!
  • Quiet! By Bill on 11/2/2013

    Was previously using a maxi-jet 1200 to run my BRS reactor. After a few months of use it seemed to have lost a lot of power. I took BRS's advise this time and went with the Cobalt, so glad I did. I noticed more flow initially than the maxi jet had but the best part, it is soooo quiet! I'd never choose a maxi jet over a cobalt again!
