Replaced the stock pump on my JBJ 20 which was 265 gph for the Cobalt 1200 295 gph, big improvement in flow and this pump is silent. Very happy with the result. Fit perfectly in the back compartment.

I received this pump first with my order of the BRS GFO&Carbon reactor, and its a great handy little pump. I have recently ordered a second one that I will be using as a transfer pump for water storage.
Its a great pump for many applications!

I have 3 of these running in my tank. 2 are set up as power heads, and the other is hooked up to my carbon reactor! I love them!

I use it for my gfo carbon reactor. And to do water changed when I pump new water back into tank. Works well.
better than the Marineland MJ1200 By Ken on 1/25/2015

I have noticed the quality of the Marineland pumps has been going down. I use them for mixing and pumping my new water. (1/2 inch ID hose fits perfectly). I took a chance and ordered the Cobalt and am happy i did. They are quieter and seem better built so far.

I purchased this power head to power my BRS dual reactor. When I purchased it I though well if it's not strong enough to drive the dual reactor I'll use it for dipping coral. Well need less to say its to powerful for that. It drive the dual with no problems, and ad a matter of fact I had to dial it back quite a bit to get the flow correct for the GFO

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.

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.
