Purigen in media reactor?

I think jc1119 was gonna do it on his tank. Not sure if he did, or how it turned out....scroll down to post #38...

I know Purigen floats... this would be a deal breaker, right? All of the reactors I have seen, the input is from the bottom with the water going up through sinking media. Also, its extremely fine, almost like dust. Even if you had a top down unit for use with floating media, this stuff being super tiny would leave the reactor.

Or do the reactors have a filter screen? If so, it would have to 100 micron..

It is actually a much more effective way of using Purigen since the water flows past all of the material instead of just the outer portion of purigen in a bag. Problem is that it is extremely small stuff and very light so keeping it inside the reactor is tricky, but can be done with the right water flow and perhaps a sponge to block it.
