I can see torches, brooms, and pitch forks waving. I thought play sand
is just pure silica and better would be crushed carbonate from shells or
coral. or, a mixture. I haven't cracked my chemistry book in a long
time, but I think it may help maintain higher PH.

Although, I'm all for getting around the $60 for 20# of live sand. It
just seems wrong. I would think that beach sand w/ crushed shells from
any source would work just fine.
