Apparently no one has tried the glass beads in a sand filter...Okay have any of you tried PERMA-BEADS. Now that's strange, I don't know how to change this.. Anyway. These are plastic or ceramic beads that you can substitute for sand in your sand filter. Apparently they are made for aquaculture and convert a standard pool sand filter into a pond/koi friendly filter system. If you've tried Perma-Beads...please let me know what you think of them.
Using Perma-Beads in a sand filter?
