  • Awesome Pump! By on 9/12/2016

    I dont know why everyone only sells the Marineland pump, this Cobalt pump is worth every penny. I've always gone with the Marineland as those are the only version sold by my local LFS, but anytime you try to restrict flow, for a reactor for example, they generate a ton of heat and noise, even just barely throttling them back. This Cobalt is silent, runs cool, and works great. I am going with these from now on. I cant speak for longevity as I havent had this pump for very long but I am extremely happy with it so far.
  • Failed after 3 weeks of use By on 4/7/2016

    Maybe I just got a bad one, Mine failed after less that 3 weeks of use. I contacted cobalt directly, they said I should soak the impeller in vinegar for an hour, I did that it still did not work. Soaked it for a full day. Still did not work. Called cobalt back and they said they would send a new impeller. That was almost four weeks ago, still no new impeller

    These are tried and true workhorse pumps. I use them for multiple purposes and they are extremely dependable and quiet. The Cobalt brand is much quieter and the build quality is superior to the Marineland version.
