Thanks for the help everyone, think I'm going to go with 1.5" of Caribasea "Super Reef" .5mm - 2.0 mm. The company's site says it's safe for burrowers, soft Bellies and sifters. figure the larger grain will blow around less.

still looking for dry rock, but I'm leaning toward MarcoRocks.

Thanks for the help, I'll keep y'all posted.
