I purchased 3 of these Cobalt Aquatic pumps at the same time after a disastrous purchase of another brand that was just the most horrible experience I'd ever had (browse my reviews to see which one I'm talking about).

While these powerheads/pumps aren't feature-packed, for the money, they do what they're supposed to do: move water around in a hobbyist's aquarium. I waited so long to review these powerheads because in all honesty, I figured they'd have failed by now: they haven't.

I've had them for over 6 months now, running constantly, in a 90-gallon saltwater aquarium. They've had no break in operation except when I'm doing enough of a PWC (partial water change) that the water level is going to get below the powerhead level. As soon as the PWC is over, the pumps are started right back up again, and everything is perfect.

While the MJ600 provides fairly reasonable water movement for their size, I do wish I'd have gotten a slightly larger version. I regret having so many powerheads in my tank, but I've stacked the live rock in such a manner that they're barely noticable. The MJ600 doesn't seem to move as much water as they're rated to do, which is the only reason I've withheld a single star from my rating.

These pumps are extremely quiet in operation, they generate extremely minimal heat unlike some other powerheads, and there are enough fittings and attachments in the box that one can set these up in just about any configuration you could possibly need.

While I probably won't purchase these particular powerheads/pumps again once these finally give out, I cannot say I'm disappointed with them to the point I wish I hadn't purchased.

This powerhead makes quite a bit of noise when it runs. To the point I'll probably end up replacing them with a different brand. Constant rattle. I have taken them apart but they still do it. They seem to pump the advertised gph. I just wish they were silent like the Aquclear powerheads they replaced.

I use this pump to power the Two Little Fishes Phosban Reactor 150. I bought it here because it was about $10 cheaper than some of the other dealers.

you can use this to power a reactor or to provide flow in your your tank. Comes with accessories that provide a lot usage options.
