 Re: Sand question
[quote author=Gresham link=board=Sand;num=1092177169;start=0#1 date=08/10/04 at 15:42:03]One thing with getting sand from places like that, is debris and possiable contamints as well as many are silica based (sharp edges, not good for micro fauna nor bottom dwelling fish). *Aragonite helps buffer you water parameters and is a preferred substrate for many micro fauna. *Some worms, cukes and such, can process the aragonite, but not the silica. *South Down, at least in the SE parts of the states, is mined from the same mine as Caribsea's stuff.[/quote]
So it is desirable to have an aragonite based sand it seems. But is there a danger to having a silica based sand in a reef tank?
