check this out if you run MJ powerheads on a wave maker

[golfish]

I saw the guy at the new LFS do this today with an old MJ powerhead. He cut the output off the impeller housing and switched the powerhead off and on. It would shoot to the right, turn off, turn on and it shoots to the left. Eveytime he turned it on and off the direction would change. Its a pretty neat mod if you run MJ's on a wave maker.

If you run 2 powerheads it alomst like running for with this mod

I heard it was posted on another BB. I've never seen it so I thought I would share it with the guys\gals here who run this stuff.

here's a few pictures of the housing before it was cut and after

Hey that's interesting; running 3 on my wavemaker and 1 full time this could increase the randomness of flow from them.

Its really a good mod. I wish I knoew about it years ago.

How do you get the housing to sit loose enough to turn? The ones I use I can barely turn by hand.

I don't think the housing turns... it is just a random flow from the force of the impellar... Since it is no longer rifled down a barrel you will get a more diffuse current....

I have used a pair of Hagen 802,s like that. I broke the nozzle,s off by accident though.

You have to see it to believe it....one time it shoots the the right, the next to the left.
