Mineral stones/rocks

[Joe Fish]

Anyone here from North Carolina? When I was there a few years ago I did that thing where you sift through the gravel from the mountains to get gems or whatever. Would those rocks I collected be good or bad in a marine tank? I was thinking about putting in some of the smaller stones.

Im assuming there long dried out and have nothing living on them. Just boil them for a little to make sure there clean and I dont see a problem with putting them in.

A word of caution. Do not put any stones that look metallic in your tank. They probably contain heavy metals in them.

they might leach, depending on the kind of material...I would recommend against it unless positive of their makeup and whether they are safe or not.

Ok, i'm not going to chance it.

Bad idea. Lots of minerals are not stable in salt water, and = poisoned tank.
