  • KoiCure Instructions

    Directions for Use

    Recent studies suggest that long-term baths at 10 ppm for 6–12 hours can be as effective as short-term baths at 25 ppm for 1 hour, with reduced fish stress (Kawai et al., 1987, Journal of Fish Diseases). Consider this when selecting a treatment method for your koi.

    Dip Method

    • 25 ppm in 50 gallons requires approximately 4.73 grams, rounded to 5 grams for easy measuring.
    • Treat fish for 1 hour in an isolation tank.
    • Ensure adequate aeration and monitor fish for stress.

    Prolonged Bath Treatment

    • Use 5 ppm (19g per 1,000 gallons) of pond water.
    • Maintain treatment for 3 to 5 days, followed by a 25% water change.
    • Recommended for mild infections and recovery enhancement.

    Short-Term Bath

    • Use 10 ppm (38g per 1,000 gallons) of pond water.
    • Maintain treatment for 6–12 hours, depending on severity.
    • Only for severe infections; monitor fish closely for signs of stress.

    Medicated Feed

    • Mix 1g of KoiCure per 1 pound of koi food.
    • Dissolve KoiCure in a small amount of water and coat food evenly.
    • Allow food to air-dry completely before feeding.
    • Feed once daily for 10 days.
