Hello,

We are working on a new stream table and are wondering what medium you found to be most useful; walnut shells, sand, or something? What are the advantages and disadvantages of each.

What method do you use to resurface /re-level the material on the table? Do you have an automatic system that flushes the table ever so often or are you not concerned with leveling it?

Thank you,

Donna
