    MJ mods

    After doing some reading on rc and reading all the reviews there I cut off the output nozzle on my MJ's and am very happy with the results.

    Now what other mods can you do to the MJ's?

    I saw Johnny Rock's posting about his MJ's that are for sale being moded to work with the wave maker. does this just involve glueing the impeller to the motor to get rid of that clicking sound?

    I made my openings a bit larger so head on they actually look like a rectangle but i really wanted to difuse the flow as I have 4 mj 1200's in my 60g.

    why would you need a wavemaker to use the mod?

    Maybe I don't get 100% what it does. Cutting the nozel off would make your flow more wide and less power right?

    Pat you basically just cut the nozzle right? How much better is the flow? Also has anyone used this wave maker: Blue Line Tsunami Wavemaker?

    the flow isnt better, as in it doesnt increase the amount of flow.
    the flow isnt directed in one spot. it does still flow mainly in one direction but its more difused.

    if you wanted the flow to be high in one spot, then leave it me. from what i read it seems a some people would mod 2 and leave 2. But i have pro3's for continual flow so i modded all 4.

    now as the impeller can start spinning in either direction, everytime they turn on and off the direction of flow can change by 70-90 degrees further increasing the benifit fron having them on a wave maker or timer.

    The best mod for the MJ is the Tunze mod. Links one, two, or three will show you how to do it. To keep the flow low just use a smaller or lower gradient propeller.
