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.

Maxi-Jet Aquarium Power Heads is rated 2.8 out of 5 by 31.
Rated 1 out of 5 by from It runs in reverse (Marineland Maxi Jets 1200) I bought this a year ago at PetSmart. I am using this for water circulation using part 6 and 7. The Properler runs sometimes in reverse. I clean it several times and still runs in reverse.

Rated 4 out of 5 by from Little to no air coming out I bought this maxijet 400 about 4 months ago and it worked fine with the air coming out. Now the only time I get air is when I have the pump basically right at the top of the water. Any help would be much appreciated thanks.

Rated 4 out of 5 by from Work Good But.... I love this product, I have it working on my 55 gallon Marineland start up i purchased on December 2015,I purchased the 600 model about 8 months ago, It was working as the wave maker set up but about two months ago when i switch to the power head with the air tube connection it work good for a while but now it make a grinding sound, if i switch back to the propeller stile it works fine no noise at all. Really don't know what to do to fix it if you guys could I would appreciate a help.

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.

Do these products have the ability to be adjusted... is there a range of power for the flow?

Asked by: Qxs8363
Not in regards to the flow rate, no. They are multi-directional, however, so you can set the direction the flow will move in. Also, you can elect to have air bubbles or no air bubbles. BREX

how do i replace the impeller on the polishing filter pump?

Asked by: Mike Aaron
Hi Mike, If you have the Magnum Polishing Filter, it uses the Maxi Jet 1200 powerhead. The filter is a new item, and the impeller is under warranty. I will email you directly. BREX

I have a small '10gl' tank at work, and I need a small power head for it, I have an Aqua-Tech 170gph power head but I have to turn it off when I leave because I think it will exhaust the fish. is there a smaller version? I love my powerhead!

Asked by: Neoma
Hi Neoma, No, that is the smallest one that we make. You might add a sponge filter to the intake of it to reduce the flow somewhat or switch to an air stone instead. BREX

How do these power heads work?

Asked by: Sonny 539
They work like any other powerhead - they are to be submerged completely. If you wish to also have air bubbles, submerge them no more than 2", and leave the venturi tube and knob up out of the water. Otherwise, remove those, and cap off the venturi, then submerge them anywhere in the tank to increase water movement. Many saltwater enthusiasts use them to create water flow over their corals. BREX

Is Marineland® Maxi-Jet Water Pump 1200 to strong for a freshwater water tank that is 60 gallons or should I with the maxi 400

Asked by: Smiley aka ronald
That depends on what you wish to achieve and what types of animals are being housed, but in most cases it would probably be too strong. You could certainly use the MJ 600, however. The 400 is pretty small for a 60 gallon. BREX

I have a 29 gal tank, ugf with the Maxi Jet 1200 ph attached to the ugf tube. I have danios and black phantom tetras in the tank. The tetras seem to have issues swimming the length of the tank. Is this ph too strong? What size do you recommend?

Asked by: Natalie2017
Definitely too strong for this size tank! We would recommend either the MJ 400 or the MJ 600, maximum. BREX
