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 28.

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.

I have a sea clone skimmer with maxi jet 1200 on it and the blades on the impeller keep breaking off. I have replaced 3 in a year. Is this normal?

Asked by: Dale2121
No, your impeller blades should not be shearing off like that. Make sure sand, small pieces of crushed coral are not being pulled into the powerhead. BREX

What size do you recommend for a 20 gallon long fish tank?

Asked by: vincentl331
Thank you for your interest in this Marineland product! That is dependent on what you are trying to achieve with adding one to your tank, but in most cases, the smallest one, the MJ 400.BREX

I have replaced a power head for the third time,why does it rotate in reverse 

Asked by: Grrg
Thank you for your inquiry. If you are using it in propeller mode, it has to rotate in reverse to achieve movement of the propeller and the high flow rates. We have not received customer feedback indicating that this occurs in impeller mode, which it should not. That would be most unusual. BREX

I have older maxi jet filters. I don't see it on site. Does the mj600 impeller work on the mp600 pump ??

Asked by: Rudy1996
Unfortunately, no, it will not. The new Maxi jet powerheads use a totally re-designed impeller these days.BREX

Is the Pro 600 or 900 impeller cover outtake or output tube fixed in its position, or, can it be rotated in the horizontal plane to accommodate coupling to a Reverse Flow Elbow for an under gravel filter. The Reverse Flow Elbow has an i.d. of 7/8 "

Asked by: koolbreeze
It can be rotated, but is 1/2". BREX
