Beach Sand what's needed besides bleach?

Are you collecting sand from a beach local to you? In MD?

As I understand it the sand from this area will be different from sand in FL for example. Silica vs Aragonite. Always though silica sand was not the greatest for our reefs.
 
The silica sand up north won't hurt anything in the reef, just won't provide any buffering capacity.
 
There have people that thought it contributed to silicate levels and subsequently diatom blooms. However, that requires an incredibly low pH that would also dissolve the silica based glass ;)

I avoid our beach sand here in the Panhandle and used to avoid it in Ft. Lauderdale as well. Way too much Panama Jack and Coppertone in it not to mention skid marks from those string bikini's.
