Koi & Goldfish: Other Treatments & Medication
SALT
Non-Iodized table, rock or ice cream salt.
No YPS – Yellow Prussiate of Soda
AS A TREATMENT
- Add 3 pounds per 100 gallons (0.3%)
- Add slowly over 3 days & leave in for 2 weeks
- Remove through regular water changes
Some Costia infections on imported koi can be resistant to this level of salt.
It is ok to increase dosage to 6 pounds per 100 gallons (0.6%)
Precautions:
- 0.3% will not harm hardy lilies, papyrus, irises, etc. However it can damage or kill plants that get nutrients from water such as hyacinths, anachris algae, cabomba, eldodea, etc.
- If you are using 0.3% – 0.5%, it is best to put fish in separate container of pond water to treat so as not to harm plants.
- Large die off of algae or plant material can cause increased oxygen demands during treatment.
- Do not leave salt in pond all year long as some parasites can become resistant.
- Do not allow fish access to undissolved salt.
Recommendations:
Treatment once in Spring & once in Fall as a preventative
As needed for outbreaks of infection
AS A BATH or DIP
- 1 pound per 10 gallons
- Leave fish in bath for 2 to 5 minutes
- Watch for signs of irritation
ANTIBIOTICS
Precautions for Amikacyn, Azactam and Baytril:
- Apply by weight of fish
