What to do with some bioballs?

[reefer60614]

So I have a bag of bioballs that no one seems to want. Any ideas? I was thinking they could be used in the bottom of planted pots to provide some drainage assistance.

Any creative ideas?

Perfect application!

If you ever set up a planted aquarium with co2, you can use the bioballs in a pvc co2 reactor.

The drainage idea is great though. Never would have thought of that.

Ha, we should sell bio balls under some different name with a marked up price to garden enthusiasts.
