Add one pound per 100 gallons when setting up a new pond. This dose results in a salt level of approximately 0.1%. Hardy pond plants can tolerate salt levels up to 3 pounds per 100 gallons (0.3%), a level which is effective for treating some diseases. For treating stubborn cases, carry out treatment in a separate container and treat at 4-6 pounds per 100 gallons (0.4-6%).
Pond salt does not break down and is only removed from the pond by flooding (overflow) or water changes. In either case, sufficient salt should be added only to compensate for the amount of water lost or changed. If you are unsure of the dosage or of the volume of your pond, have the salt level checked by a pond care professional. Overdosing may cause harm to plants or fish. Store in a dry place. Not for human consumption. Keep out of reach of children and pets.
