Great Little Pump By cbsopp on 5/6/13cbsopp would recommend this product to a friendI have two of these...one for my dual reactor and one for extra flow in my refugium. They work flawlessly.
Great pump By SPS on 3/12/13SPS would recommend this product to a friendThis is the best pump out there.
Maxi jet1200 By Paul Dinonsie on 2/26/13Paul Dinonsie would recommend this product to a friendGreat pump and had it super fast I ordered the BRS. Gfo reactor deluxe and thought I ordered the one with the pump but accidently didn't so they gave me the pump for the price that would of veer if came with package
Bad pump By David on 2/23/13David wouldn't recommend this product to a friendI kept getting shockin my my tank and couldnt figure out why. Well yesterday my coral was mad and retracted and I woke up this morning to all my coral still mad and all my inverts dead. I did a water change even though my water parameters were fine.
I had this pump set up with a BRS single reactor I went to change the media today and was going to unplug this pump the power cord had melted where it goes into the pump and was emitting electricity into my tank and not only killed alot of my inverts but was shocking me as well. I would NOT recomend this pump to anyone!
Should have bought this pump the first time around By Dave on 12/21/12Dave would recommend this product to a friendRecently I ordered the Carbon and GFO cannisters from BRS and trying to save some money, I went with another pump. Lets just say that pump didn't perform and is not in the trash can.
I set the Cobalt pump up and I have had zero problems with it. I wish I had ordered this pump the first time around.
Impeller Failure By Rick on 11/20/12Rick wouldn't recommend this product to a friendI purchased the reactor/pump combo exclusively to regenerate GFO
The impellers apparently do not hold up to the lye-water required to regenerate GFO. I've gotten less then 72 hours of operation out of each of the 2 impellers I've used. (a 10 year old MJ1200 holds up just fine)
I gave it 3 stars because Cobalt was very good about the original replacement part. I'm hoping they are going to replace my second impeller with the same top notch service that they did the first.
Reliable By Scott on 10/4/12Scott would recommend this product to a friendStill running strong over the last 7 months. I have the nozzle set to push water out prior to entering the reactor line and this has added nice water movement. Good pump.
Best for reactor! By Grant on 9/10/12Grant would recommend this product to a friendI had to order this separate from my BRS dual reactor because it was out of stock. It works great though.
Only problem i have had is if a piece of algae gets caught in the intake it significantly reduces the flow, as any pump would..
Also make sure the suction cups are securely fastened or the vibration can get kind of noisy.
same old maxi By Quenton on 9/5/12Quenton would recommend this product to a friendi was looking for a replacement part for my maxijet and couldn't find it i called BRS & THEY had the answer for me! This is the same maxijet pump thanks BRS
Way better than Marineland By Ryan on 8/20/12Ryan would recommend this product to a friendI bought this pump to replace a loud marineland pump that was being used in my reactor. it was a direct replacement (MJ1200 for an MJ1200) and the difference was night and day. I use this pump to pump water from the back of my biocube, into the stand and back up. it's dead silent even with the 4ft of head height and you can even regulate the output without chattering like the Marineland. I'm placing an order for another one now to replace my marineland return pump.
good value for your money By Nicholas on 6/18/12Nicholas would recommend this product to a friendvery nice pump...Its nice and quiet and very reliable. This is definitely like the originals
Great for reactors By Greg on 6/12/12Greg would recommend this product to a friendI 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.
