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.

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

I purchased 2 maxijet pro 1200's. I was going to use them for additional circulation in my 10 reef. The one I opened is SO noisy i cannot use it in my tank. I have tried to re-seat the propeller many times to no avail..Please advise..Thank you

Asked by: Richy
As it starts up, it will definitely make some noise for about the first 10 seconds, then should go quiet. If you have it on a wave maker or something along that line, I would not recommend using it in that application. If you are using sand, unplug it and take it apart to make sure sand has not gotten up into it. Other than these tips, please call us so we can troubleshoot it for you. 1-800-322-1266.BREX

Have a 39 gal eclipse show tank power head that disperses water across filter in hood is out do you have replacement? If so what is price? Thank you 

Asked by: Jeff b
Here is the item that you need: It will not come with an impeller or an impeller cover, so keep your old ones. The price is $39.06.I would recommend pulling the impeller out and cleaning it and the pump first, if you have not already done so.BREX

Will this pump works for my SeaClone protein skimmer model 150?

My SeaClone protein skimmer model 150 is on and off every other minute. I had replaced the impeller once and now the pump is working on and off. I wonder if this pump is compatible with my protein skimmer. I have 60 gallons tank with corals and fish.
Asked by: blezzedguy
That skimmer takes the Maxi Jet 1200 with a special adaptor. If you buy the powerhead as such, you will need to keep your old adaptor as a new powerhead will not come with one. Try soaking the entire powerhead in distilled white vinegar to see if this will remove deposits and get the powerhead functioning properly again. It still sounds like an impeller issue, but there could be deposits in the chamber the impeller resides in as well.BREX

maxi jet powerhead

i'd like to know how to choose a powerhead size? not sure if the 2 i've tried are good55 gallon tank
Asked by: Jojo3
There isn't a real formula for choosing one. It is based on what you want to use the powerhead for in your tank. You can basically look at the gph of each powerhead, and go from there. Determine how much water movement you may want or your fish may tolerate. Also, do you want just one or are you placing one at each end of the tank? That affects what you choose as well. As it sounds like you want two, the 600 or 900 would work, again, depending on what they are going to do in the tank.BREX
