hey i tried looking this up online somewhere but no luck on anything aquarium related. i recently went to the rock nursery near my house and they had rocks names "three river stone" and its supposedly from idaho. i boiled the rocks already and put vinegar on it and no reactions. i was wondering if this is safe to add to my aquarium? any help is appreciated

The name implies it came from a river... on reaction from the vinegar.. if it has no iron in it you should be good, is the rock like river rock.. ie smooth and rounded?

Just picked it was your first post!

THREE RIVERS FLAGSTONE

Three Rivers flagstone is an argillite stone with a swirl pattern of gold, tan, beige and plum unlike any other. Formed in the high altitude of the Sawtooth Mountains of Idaho, Three Rivers stone is a very hard material ideal for pool decks, driveways and walkways.

I googled it and this is what I found. it looks like a very pretty stone. It should be safe for the aquarium. Looks like it would be great for a terrace or a waterfall or even a backdrop.
