Live Sand swap?

[SteveW]

I've read in a number of places a great way to increase the biodiversity of your reef would be to swap a cup or so of live sand with other hobbyists.

What do people think of meeting at a local fish store like Big Al's (I live in Richmond) and swap a cup of sand? Doing this a few times with different people over time would probably make for an interesting experiment!

Each person doing so should do so responsibly: ie not participate unless their system is currently disease free.

What do people think? Any takers?
