I bought two to these for my BRS reactors. They became less noisy after about a week of use. It is a solid pump and easy to clean.

Well I've been using the marineland MJ1200 for a few years now (the older Italian made one, not the Chinese made one) and these seem rather comparable. They do what they are ment to do reliably.
However, my pump was missing the venturi piece, luckily I had no intent of using it, but had I wanted to connect the flair to the end of the pump, I would have been out of luck.

Same thing as MJ1200 but made to higher standards. Is much quiter but no Hi flow fan upgrade kit included.

I've recently purchased and used both the Cobalt and another brand MJ1200. The Cobalt runs more quietly and includes most of the same accessories as the other version, however this Cobalt included only and impeller and not the propeller accessories so keep that in mind. Overall I prefer this pump to the cheaper version.
