Aqua charger needle wheel

[bassnman11]

In the Foster & Smith catalog they habe a biomedia thing called a aqua charger. Does the same thing as bio balls. I have not seen one in person to determine size or construction. Have you ever seen one? If of proper sixe, looks like it would make a killer impeller for a needle wheel conversion.

i dont think that would work very well. i have done alot of needle wheel designing. and that would have alot of resriction to the flow of water.
