You have been advised, so don't complain By Mike on 3/29/14

BRS was very upfront it letting any buyers know that this pump will make noise if used in a back-pressure application. I purchased them because I was more interested in using them as a low-cost wavemaker due to the fact they are also packaged with a propeller style impeller and a shroud that fits it. When I assembled and tested it this way, I was disappointed at the loud buzzing sound it made when running. I then discovered why: there was a manufacturing issue with the magnet attached to the propeller. The hole for the shaft was slightly off-center, so the propeller assembly vibrated when running. I observed the magnet for the standard impeller in the kit didn't have this flaw, so I just pulled the parts apart and swapped the magnet portions, and problem solved. Yes, these pumps in propeller mode can chatter somewhat on startup, but if used in a continuous application this shouldn't be too much of a bother.

Not as quiet as the old MaxiJet pumps. Makes noise when used to mix saltwater and even more noise when used with a reactor. Spend a bit more and get a pump with a ceramic shaft.
Not good By gatorGRAFIX on 12/25/13

I bought one of these as recommended in the BSR video for the Deluxe GFO reactor. Hooked it up in my sump and plumed it as in the video. It IS loud and it will hardly tumble my GFO at all unless I fill it about 20% full. Tech was no help either. Very disappointed. Guess I'll have to spend more money on a better pump. Fiddled with it for weeks. :(

MJ's have always been reliable. I hadn't bought one in years and wow, it comes with a lot of attachments now to convert to whatever you want. Well worth the cost.
Shocked me after about a year of use for water changes By Dangerous on 8/6/13
Dangerous wouldn't recommend this product to a friend
I used this pump to perform routine water changes for about a year. One day I was doing a water change and went to pump the new water into the tank and there was a loud popping sound which resulted in a strong shock and smoke coming out of the unit. For some reason the GFCI did not trip but I will never buy one of these pumps again.
Makes water changes super easy! By Stephanie on 7/24/13

Used this in the powerhead configuration for water changes. The only reason I gave it 4 stars is because it's a bit bulky. Works well otherwise.
LOUD........ By Tim on 5/29/13
Tim wouldn't recommend this product to a friend
This Maxijet is OK as long as you are not running it under any type of load such as a media reactor. If you do it makes a very loud noise.
I would recommend using the Cobalt pumps if you are running it under any type of resistance.
great pump By justin on 3/26/13

Quit your winning if you can't handle the 3 seconds of noise on start up then why are you spending $30 on a pump.this thing moves massive amount of water in the circulation mode.these pumps are meant to be ran wide open not restricted.I have mine running in powerhead mode with a hydro flo water deflector and have never seen so much water movement. I spent $40 on a system that moves as much water as mu buddies $500 system.

The maxi jet 1200 is good and versatile little pump. I use mine as a circulating pump to mix saltwater and to refill my tank during water changes. Hard to beat for the price. I use the 600 model to circualte my ro water as well.

I connected this pump and ran it for about an hour to run my dual BRS GFO/GAC reactor, and there is no way I will continue to use this pump. You could hear it from every corner in the house.
Effective little pump By Joseph on 1/7/13

Purchased for use with my BRS reactor. Solid little pump that survived getting pumped around in my sump w/o complaint.
Perfect flow rate for the BRS GFO/CARBON single reactor.
(never noticed any noise, but it was sitting in a sump contained in a thick wooden base)
Nice pump for a reactor By shaungee on 12/28/12

I picked up this pump to power my BRS biopellet reactor and it definitely has more than enough power to do it. The only issue is when I had to throttle down the pump to get the right tumble in the reactor, it hums noticeably, not too loud, but you can definitely hear it. I got the prefilter kit to keep debris out, and altogether had about 35 bucks in the setup, so taking into account the light hit to the wallet, the humming isn't that bothersome!
Very quiet By Mike on 12/20/12

These seem to be the Italian made version which run much quieter. BRS could send the cheaper versions and have met their description, but sending me these reminds me what a quality company BRS is. Thank you for spending a few extra bucks to get the higher quality powerhead. You clearly are looking out for us reefers. I run them on on all 3 of my BRS reactors with zero issues and silence.
power not worth the noise By BB on 12/17/12

This product does push plenty of water through my brs carbon reactor, but unfortunately I have to say that it's short life in my sump is about to come to an end because not even my mag drive 18 comes close to the amount of noise and vibration coming from this pump. I definitely would buy something of a better quality, which is unfortunate with a brand as well known as marineland.
little jet big power! By Dallas on 11/3/12

Bought two of these for my 70 gal reef tank these thing push crazy amounts of water works well in my tank only down side is takes a couple seconds to start while making a loud grinding noise but ones running nice and quite. Suction cups could be better wish they had magnets instead be sure to check often cuz they will lose there suction and fall making a blizzard for your tank. Other then that awesome powerhead for the money

This pump shocked me as I was working on my sump. Im glad it was not in my tank because my fish would have died.
Great pump if you're not using a controller By jeremy on 8/27/12
jeremy would recommend this product to a friend
Circulation pump - pros- this thing creates a ton of flow, I was really impressed with the current this pump makes.
Cons- if you are using his pump with a controller it can be quite noisy when starting or if the power goes out when it comes back on its noisy.
Power head - pros- as a power head this pump performs as expected, my pump pulls double duty mixing small batches of saltwater and as a circulation pump with no problems.
Cons-none so far
Utility pump- haven't used this as a utility/ return pump yet. I can imagine it would work ok in an application with minimal head height where not a lot of flow is needed. Maybe in an ATO setup...

Purchased a Maxi Jet 1200 to run my dual BRS reactor. It works well with the reactors. It seems to be very reliable and is priced just right. It can be a bit noisy, but mine is in my sump area so the noise is not an issue....

I got this for the Dual BRS GFO and Carbon Reactor.
This pump is the loudest thing in my 90gal system. I would not recommend it. It noise and vibration from this pump is so noise that I have a hard time telling if anything else is on. I can hear it over the TV.
I would not recommend it for anyone.
