Can be used to treat fish and plants

Potassium Permanganate mixed with water to make a light paste can be very successful in treating wounds.

The only disadvantage to using the paste is that the wound will be stained a dark purple for a couple of days which makes it harder to tell if the wound is healing.

Often times new plants will have parasites on them so you will need to treat them with potassium permanganate before you introduce them to the pond.
