Alternate Impeller for MJ900?

I'm pretty sure the MJ1200 impeller will fit the MJ900. Thereby making the 9000 a 1200 and increasing the flow to 295gph.

I'm not really after the increase in flow. Otherwise I'd buy one of those mod kits to make it flow lik 8 million gph

What I'm after, is a NEEDLEWHEEL impellor that will fit the MJ900 or MJ1200.

Does anyone know if any of the nedle wheel impellers will fit the MJ powerheads?

Thanks

Re: Alternate Impeller for MJ900?

It's so tempting to buy the needlewheel for a Rio or some other powerhead. Might work. Probably cost me $15 to find out.

I wonder if it's possible to mod the stock impeller assembly on the MJ1200? I'm thinking I might drill a few holes in the blades or saw some grooves in the blades. Maybe that would chop the incoming water a bit more?

I don't care about the loss of flow from modding the impeller blades. This is for the 10g fragano (thanks Biff--she gets credit for coining the phrase) . Even if I loose 25% of the pumping volume, it'll still be a lot for this size tank. It's the pump thats plugged into my refugium.

Re: Alternate Impeller for MJ900?

Worst thing that could happen,is have to buy a new impeller.So its worth a shot.
