Looking to stock a new tank in a short while and looking for substrate. Ran across several threads about a "White Aragonite Reef Sand" located on eBay. Doing a bit more research on the vendor shows a plethora of different thoughts on it. One person states it is dolomite in his opinions, others state that it may be altered aragonite (I believe Randy Holmes-Farley may have actually taken part in that thread 9 yrs ago).
So, lets say it is dolomite. Any ill effects for a SPS reef tank? Again, some say yes, others say no. Some say aragonite is better at buffering, while others say that neither do exceptionally well as the ph point to dissolve is too low to begin with. Im curious to know if its all an old wifes tail, or if aragonite is really better than dolomite for a reef.
