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.

The Maxi-Jet also contains an 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 1 out of 5 by from Terrible for my Application I bought a maxi jet pro 400 to use as an external pump to drive water through a small nitrate filter and it flat out doesn't work. Marineland markets this pump as a 3 in 1.......powerhead/water circulator/utility pump. It even shows in the instructions the pump used externally (non submerged) Okay, problem with this omni directional mount leaks, or more so, all it does is suck air in around it.....that's fine (well not really) if its submerged, works fine as water circulator and great as a powerhead, but use this pump out of the water it sucks so much air around the omni directional mount that it can't even pull water the length of 3 inches! That is totally ridiculous. Marineland makes some very fine products I just wish they were more up front with the capabilities of this pump, external utility pump is one of their selling points. Wasted my money. Needed EXTERNAL pump.

Rated 5 out of 5 by from Great product The maxi jet 900 is awesome! I have 2 for my 55 gallon and the fish and corals love it! Had issue with my first one and Marineland sent me another one free of charge. Great company and great product! Will be buying other products when I get a 100gallon tank.

Rated 5 out of 5 by from Great pump, but NOT WAVEMAKER using PROPELLER I've been using these pumps for years to alternate the flow direction in my reef tank (a.k.a. Wavemaker mode.) These pumps, using the standard impeller, do this well. They make one short "click" when started. The new propeller add-on chatters at start up, from one to five seconds. The propeller would make a great circulation (always ON) high volume pump but no way does it work with short duration (10 to 15 second) run times. It takes way too long to engage, making a loud racket the whole time. Be careful, as some vendors are labeling the propeller configuration as a "wavemaker." Note: I had previously tried the after-market add-on propeller kits, and they had the same problem. Marineland: great product; need to figure out how to "soft start" the pump.
