MTM nozzles from Mazzei are like little eductors that screw into regular PVC threads. Mass Transfer Multiplier nozzles work very much like an eductor to convert high pressure water flow into more water volume movement but the Mazzei MTM nozzles use no flared trumpet and are way more discreet to use in a display aquarium. The smallest MTM nozzle is still 1″ thread and requires pressure differential of 5 PSI and 400 gph or greater to achieve high MTM rates so these are definitely not well suited to smaller aquarium sizes. Also, without the a flare to disperse the water jet into mass water movement, you’ll likely need at least 18-24″ of empty space for the jets to decompose into more suitable aquarium flow, the kind that doesnt immediately shatter your precious fuzzy sticks. These jets would be perfect for producing gyre flow in larger aquariums and encouraging more mass water movement from a high pressure closed loop system. So far we’ve only seen the jets available from Aquatic Ecosystem and for more information please visit the Mazzei website on MTM nozzles. Something also tells us that an enterprising DIYer could re-purpose these air and water mixing MTM’s into the perfect air injection nozzle a-la AquaC protein skimmer, we hope they send us pics of the first MTM protein skimmer.

I don’t understand how this works. It looks like a nozzle that creates more laminar flow at a higher velocity. This is counter to the random turbulent flow we are trying to create, or what a normal eductor creates. When you go on the website, it states that it is used for dissolved gas treatment. Which makes the AquaC reference make sense.
This nozzle along with eductors helps to transform your water flow outlet into the type that moves all the aquarium water as a whole, perhaps into a gyre. ALthough it is true that we want turbulence to increase gas transfer mixing, this is important at the finer scale. Faster flow is most important for increasing fine scale mixing/turbulence. It is much easier to produce fast laminar flow than fast turbulent flow.
Alright Jake you need to get your hands on these and compare them side by side with educators to see if they work as advertised
I don’t do educators personally because I hate the trumpet sticking out, but these guys are so compact they really might make me rethink it if they do work as advertised *ahem*
