With this aquarium circulation pump, power head and utility pump in one, you'll get more value for your tank.

Maxi-Jet® multi-use water pumps are three pumps in one: power head, utility pump, and now featuring a circulation pump option.  Still the best power head for powering undergravel filters and running wave maker timers, as well as for running small fountains, calcium reactors and skimmers. 

New to the Maxi-Jet, the in-box conversion kit, which can turn the power head into a prop style circulation pump for ultimate water movement inside the aquarium--using the least amount of energy!  The Maxi-Jet is the most fully adaptable pump available.

Rated 4 out of 5 by from Powerfull but breaks impeller when used with wavemaker I love this pump and recently purchased 4 of them for my 125 salt tank, I also wanted to use it with my wavemaker and so plugged all 4 into it and started them up. They were working just fantastic and kept the water in the whole tank moving and the tank was crystal clear, after about 3 weeks of use I started seeing algae growing on the rocks and glass so checked the filter media, that was clean.So I put my hand in front of the first pump and realized that it was running but pushing NO water, so checked the other 3, those where the same. No water movement from them. So took out the first one to see what was up, well, all of the wings on the impeller where broken off at the base, as where the other 3 pumps. Even though they advertise that they can be used with a wavemaker, I found that they can not. It has reached over the 60 day mark to have the impellers replaced so now have 4 not working and need to buy new impellers for all 4 before they can be used. And NOT with the wavemaker, which is what I wanted them used with. Wish they would put a warning on the information section that they will break if used with wavemakers, and stop advertising that they can be used with them.

Rated 3 out of 5 by from good for circulation, poor impellers I had the 1200 set up as a circulation unit and it worked well enough, then when I added fish to my tank I set it up as powerhead for circulation only.. the impeller only lasted 3 hours! I went to a basketball game afer I set it up and when I got back there were purple impeller blades laying on my tank floor, and no circulation... cheap!

Rated 1 out of 5 by from Needs Improvement It has great flow when it works. I got it because of its multiple uses though its been in impeller mode for 6+ months now. I have it always on, it chatters on start up, and though thoroughly cleaned I keep finding it off at random times. The suction cups don't work worth squat. I tried using it as a circulation pump in the display but it would fall off almost daily and end up blasting my coral or flinging sand in the water collumn. I regret this purchase.

Rated 2 out of 5 by from Air intake does not stay attached Poor design for the attachment of air intake. Needs to be a tighter fit or seallant must be used to attach the air intake. A small design change could eaisily fix this.

About 3 months ago I purchased a Maxi-Jet 900 power pump that I use as a circulation pump. Can I get a an impeller replacement. The impeller that came with the unit does not turn any more, the impeller is broke

Asked by: Ackee Bud
If it has seized up, try soaking it in white vinegar for about 15 minutes, after removing any and all debris. If it is a manufacturer defect, such as the shaft snapping in half, contact us at 1-800-322-1266.BREX

Hi there. I have a 40 gallon (36 inch wide. 18 inch depth and 17" tall) planted tank with tetras and gouramis. Which maxijet would best suit my needs for water circulation? Thanks.

Asked by: rastamanvibration
Plants normally don't like too much movement so I would probably go with the Maxi Jet 400.BREX

I have a 50 gal tank using two Maxi-flo 600's that need replacing These are used for a two plate under gravel filter. Is this still the recommended type for this type filter? Should I add a third 600? Or maybe use two 900's instead? Thanks,Dennis

Asked by: Chromeboy
I would use either the Penguin 660s or the Maxi jet 600s, either are perfect for this application.BREX

What is the voltage of your pumps.will the voltage be viable in Ireland @220 volts

They are 120 volts, and no, they will not work at 220 unless you have an adaptor. Additionally, we do not sell direct, unfortunately.BREX

Could you tell me what the difference between the maxi jet 1200 and the maxi jet 1200 pro is?

Asked by: Jacob55
The only difference is the packaging and the impeller. We made changes to the impeller in the past 6 months to a year.BREX

I have an outdoor bird bath that requires a Submersible Pump in order to circulate water. I used a MN606 Mini-Jet. Today the wire casing cracked an exposed the wires. Is this the recommended pump or would you recommend something different ?

Asked by: Lew75
That is a good pump for that purpose, but it is no longer made. It was discontinued some years ago. We no longer make a small, submersible pump like this in the Marineland line. We do make the Tetra SP 140 pump, however, which is sold through garden centers and nurseries.BREX

Hi if i use it as a sump set up like example 2 of the manual what GPH should i expect 295? thanks

Asked by: teufel
No, it does 295 gph at 0 head. That is the maximum flow rate in the powerhead mode. You would need to incorporate the amount of head you would have, which depends on the distance from the sump to the top of the tank, but it would be considerably less.BREX

I have an 120 gallon aquarium, with under gravel filters, and wanted to purchase this pump to circulate water under the gravel. How many should I buy and what size? And also, do these come with the adapters to hook them into an undergravel filter?

Asked by: TheCrazyTurtleLady
Yes, they do come with the adaptors needed for hooking them to UGFs, and how many depends on how many tubes you want to hook up, but I would suggest at least 4 of them. To get 120 gallons of water turned over at least 7 times an hour, I would recommend the MJ900 as a minium. Four of these will give you 920 gallons an hour which is between the normal 7-10 times per hour recommended for turning over the water in an aquarium.BREX
