Your thoughts?

Have any thoughts as to the use of crushed dolomite as a reef tank substrate? The dolomite in question is bright white, and sized slightly smaller than the special grade aragonite you could purchase in stores.

My thoughts are to use a remote DSB (your bucket idea) with aragonite as the SB media and use the dolomite as the shallow sand bed in the 75 gallon display. Not really looking for buffering in the display as the bed will be in the 3/4" depth range.

Reason to use dolomite is purely cost of aragonite to fill the 75 and the lack of an inexpensive aragonite playsand in my area of northern California.

Your thoughts would be welcome
Mike
