I also would agree w/the masses here and say 'no' to gravel. What I did
was
put some flat rocks in - I was able to purchase them at my local garden
supply place by the pound. I was calling it slate until I learned it was
just flat cut field stone :-)

That's not a bad idea, using slate I mean, there is a water garden centre
near me that sells nice big flat pieces that I could arrange into a simple
flat base.
