EuroReef RS180 Mod - Question?

[globaldesigns]

I have a EuroReef RS 180, it does work great, but I have seen mods where you cut the prongs of the needlewheel and then using a type of mesh, you create a different impeller that creates even smaller bubbles.

I am interested in this mod, but do not wish to destroy my impeller. Does anyone know where I could buy a modded impeller for my unit?

or

Is there a pump (suited for my unit) which comes with such a impeller? or with even more power

Any advice is greatly appreciated, thanks.
