Rocks okay?

I found a bunch of nice stackable rocks today when I went to cut down my Christmas tree.........

Do you think they are safe for my aquarium?

Thanks......

the rocks the 'sparkle' probably have an ore of some kind in them,
this could be dangerous and should therefore be avoided.

the rest looks like a mix of shale, sandstone and granite but I'd nedd pics of each one to be certain.

you can do a quick test to see if any a calciferous (which also shouldn't be used). poor a small amount of white vinegar on the rock, if it fizzes then it is calciferous.

I wouldn't just throw in some rocks if I found them. They could leech undesirables into the tank.
