Sounds like a great idea, Lee! I have a 14 gallon BioCube I'd be willing to donate for a good cause. Could set it up with a bag of sand and some liverock. I can talk to Carlos about having RCA do something, he's an awesome support and always willing to help.

Possible discussion ideas:
- Responsible buying of fish
- Auto-top off DIY demonstration
- Calcium Reactor solutions, and explanation
- Aquascaping tips, do's and don'ts
- Water Chemistry (effects of KH, Ca and pH a place to start)

Just throwing some stuff out there that seems to be things average hobbyists struggle with...
