How To Make Non Suitable Rocks Safe For Aquarium?

    I poured vinegar on them and it smoked with bubbles, so they are not safe. But is there a way to make them safe?

    Can't you just find different ones? I would think that unless you sealed them somehow it will still affect the tank.

    depends on the fish you'll be keeping.

    They're safe for hard water fish like an mbuna cichlid tank but if you are just doing a general community than I wouldn't use them.
