Well, like I said Tahitian Moon Sand is more expensive. Black Beauty is reportedly too sharp for bottom dwellers, and Eco is actually more expensive than even AS. AS is out but would you think Eco would get along with my loaches? Pricey, but at least it would have some nutrients for the plants where sand wouldn't.

FWIW the going rate at my closest ColorQuartz distributor for S grade black is $30/50#. Not sure if I can get it any cheaper with a larger order will call back and ask.
