have to jump in hear, silica sand is fine for use in a DSB, just ask Dr.
Shimek yourself. Also, as I heard at MACNA calcium based sands are in fact
not acting as a buffer. This is a myth as Dr. Shimek said, "if your calcium
based sand is actually dissolving in your aquarium, then your corals should
be melting as well." Dont beleive me, ask the Dr. at reefcentral or
reefs.org
IMHO
