anyone need cheap aragonite sand??

[Aquattro]

Troy, I've acid washed things before with success, but with the grain size of this stuff, I suspect you might be right about it dissolving. Acid dissolves the outer layer of the substrate removing the copper with it. I think this sand would disappear without the outer layer<g>.
Really sucks...apparently some local aquarium care service treated this guy's 135 full of sand and live rock with the copper. Copper killed everything in the rock, which rotted and killed all the fish and contaminated the sand to boot!!
I got it dirt cheap figuring I could clean it. we'll see.....
