Maxspect Bio-Spheres in Reactor

[psumms]

I run a bag of Maxspect Nano-tech Bio-spheres in my sump - Important to keep these clean, ideally these would be in my return pump chamber but i'm pushed for space - Any reason not to have them in a fluidised reactor fed from my return pump? I know they need to be kept packed tight to prevent wear from abrasion, but any reason for/against? I've googled but not found anyone else doing this.

I dont use bio balls in any fashion...detritus collectors...but i dont see why you couldnt use them in a reactor if you wanted.
