Can the medical stone be put in the water tank?

If it is fish farming, it is best not to use medical stone casually. Medical stone can purify water. It can purify water at will, which may be harmful to marine life, especially the fish raised at home. The vitality of these fish is generally not very strong. If you change the water at once, you may die. You can make several changes day by day, such as purifying for 65,438+00 minutes, and then pouring in a little. After a week, you can use water soaked for 20 minutes, but you can't directly change the living environment of fish with water soaked for a long time.
