Any plans for DIY needle wheel impeller?

Let's see it.

Bio ball

on Mj 900

Pic is 1-1/2 day of skimmate, not bad.

loc01 · 04/28/2006, 06:49 PM

Wow! I never thought of that. Great mod, did you have to glue that wheel to the shaft? did it ever slip off?

Thanks for sharing,

Loc

quangtam7 · 04/28/2006, 07:14 PM

No glue at all

loc01 · 04/28/2006, 08:52 PM

Huh! Did you just cut the center of the bio ball tight enough so it wedged itself to the shaft?

Loc

quangtam7 · 05/03/2006, 03:10 AM

I used a drill bit to widen the center of the bio ball.
Here is the back side of it.

Thank you the the close up pictures, now I got it.

wow, thaet's great looks like if anything you're getting TOO much foam (wet skimmate), but that looks absolutely awesome! I wonder how that compares to the more expensive needle wheels (sedra pumps come to mind).

This could work oodles on some custom made skimmer as well assuming the one pump has a strong enough venturi to make the desired bubbles, then you could simply use any other pump to swish it around inside.

Makes great skim but how does it effect the gph? more, less, or doesn't matter it makes more skim?

sfsuphysics · 05/03/2006, 12:01 PM

Well it's all about contact time, and I don't think there's as much contact time in the power head to skimmer as there is swirling around in the skimmer which is why I mentioned use it to make the bubbles, then do like the bigger euroreef skimmers and just have some pumps which only recirculate the stuff inside

biobal

its really fine but what about the bigger motors. what can we do for them. in easy way ofcourse

loc01 · 05/03/2006, 10:24 PM

I was thinking of putting this mod. maxijet inside the Euroreef skimmer, sort of recirculation to see if it works any better.

moriartiholmes · 05/12/2006, 10:16 AM

quangtam7, any pics of the pump in action? I ask because I'm curious if the MJ cover still works or if that also had to be moded. A simple "yup, it works fine" will do if you don't have a pic

impur, look good
where did you get the venture for these maxi's

loc01 · 05/15/2006, 02:15 AM

I did mine but it keeps running on and off and the impeller keeps jumping off and binding on the side. Is something I am missing here?

Thanks,
Loc

Its from the rio needlewheel pump i replaced witht he MJ.

I ended up flipping the bioball over, mounting it with the needles facing downward toward the magnet. Fixed the noise and works consistantly now.

RandyStacyE · 05/16/2006, 09:26 AM

So far I only see the "bioball mod". Anyone ever try the 3M bristle disks?

LegoZ81 · 05/16/2006, 09:32 AM

these things are monsterosly abrasive and i really don't think the composite of abrasives they are made ouf would be reef safe but who knows... i have seen them in action on my car when some body work was being done PRETTY cool

Avast Marine · 06/02/2006, 08:11 PM

Anyone know a souce for just a few bioballs? I don't want to buy a whole box just to try this out.

Pbrown3701 · 06/02/2006, 08:25 PM

I have a bunch from an old wet/dry that are sitting in my attic. If you want a few, i can send them to you - FOC of course. However, i'm new to this so you'll have to tell me a way to get your contact info.

Avast Marine · 06/02/2006, 08:32 PM

You've got PM.

Spiffyguy · 06/14/2006, 05:31 PM

I have tried this mod and it is horrible loud. Any suggestions on fixing that?

Re do it and make sure you try to get it as balanced as possible. The vibration and noise levels depend much on how balanced your impeller is.
