Using Rocks You Find?
How do you test to see if rocks you find in your area have anything that may harm your tank? I have a couple places I want to visit around my city to see if I can find some rare looking stones, but I don't want to put anything in my tank that might hurt my fish or plants.
Is there a couple test to make sure rocks and stones are safe for aquarium?
