floor scrubber pads?

[Chasintail]

Ever heard of using one or pieces for filter material? I have access to a LOT of the little circular punch outs for the floor machine pads that could be used for bio media. Anyone have any experience?

I've been using them for years and are very good.

Maxxx... using just the white or colored as well. I'm concerned about any trace materials hurting the rays.
Thanks!

My only concern would be if any adhesives were used on the pads or any kind of chemical treatment.
