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.

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

After reading through the Q&A's, I noticed that for proper operation of air bubbles the unit cannot be below two inches of the water level. Is this true, because it is not mentioned in any of the instructions or information. At least I cannot find it.

Asked by: JimA
Yes, this is correct. The further down you place it, the harder it is to pull the air into the venturi properly. BREX

Can you reduce the flowing the power heads. I recently downsized my tank and the flow is a bit too strong

Asked by: LoriD1
No, it does not have a flow control on it. You can change the direction of the flow, but not the power of it.BREX

Power head didn't come with clear instructions. How do I set it up for under gravel filter

Asked by: Fishhead6162
Essentially, there is a long cone shaped piece that attaches to the bottom of the powerhead and rests on/in the UGF uplift tube. The suction cups and bracket should still attach to the glass panel of the tank. The powerhead should not be more than 2" down in the water, and the venturi adaptor should be attached and outside the tank, to draw air into the powerhead. Please call if you have any questions at all. 1-800-322-1266.BREX

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
