Aqua Meds KoiCure™

Advanced Treatment for Bacterial Infections in Koi and Goldfish

Aqua Meds KoiCure™ is a professional-grade treatment designed to support the recovery of koi, goldfish, and other ornamental pond fish affected by bacterial infections. KoiCure is commonly used to address conditions such as ulcers, fin rot, septicemia, and other bacterial issues that can threaten fish health.

Key Features

  • Targeted Bacterial Support: Commonly used for ulcers, fin rot, and systemic bacterial infections in koi and goldfish.
  • Professional-Grade Formula: Trusted by experienced hobbyists and pond professionals.
  • Multiple Treatment Options: Suitable for bath treatments and medicated food preparation.
  • Filter-Friendly: Designed to minimize impact on biological filtration when used as directed.
  • Convenient Packaging: Available in sizes suited for 3,000, 5,000, and 10,000-gallon ponds.

Why Choose KoiCure™?

KoiCure™ offers flexibility in treatment approach, allowing pond keepers to tailor use based on infection severity and fish behavior. Whether used as a bath treatment or delivered through medicated food, KoiCure helps provide targeted bacterial support while maintaining overall pond stability.

Available Sizes

  • 25 g
  • 50 g
  • 100 g

Additional Use: Medicated Koi Food

KoiCure™ can also be incorporated into koi pellets to create medicated food. This approach is especially useful for treating internal bacterial infections in fish that are still actively feeding.

  • 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.

    DIY Medicated Koi Food with Aqua Meds KoiCure™

    Purpose:
    To support the treatment of bacterial infections such as Aeromonas, Pseudomonas, fin rot, and ulcers by mixing KoiCure™ into koi food.

    Dosage Guidelines:

    • Target dose: Commonly used medicated-feed levels based on koi body weight
    • Mixing Ratio: 1 gram of KoiCure™ per 100 grams of koi food (1% by weight)

    This 1% formulation follows established aquaculture medicated-feed practices and provides an effective daily treatment when fed normally.

    DIY Recipe – 1 lb Batch

    Create your own medicated koi food using KoiCure™ from Aqua Meds. This method delivers treatment through food with minimal handling stress.

    Ingredients:

    • Koi pellets: 448.5 grams (15.82 oz)
    • KoiCure™: 4.5 grams (0.16 oz)
    • Unflavored gelatin: 7 grams (0.25 oz, approx. 1 packet)
    • Hot water: ~1/4 cup (for dissolving gelatin)

    Instructions:

    1. Prepare Binder: Dissolve 1 packet of unflavored gelatin in 1/4 cup of hot water. Stir until fully dissolved and let cool slightly.
    2. Mix Medication: Stir in 4.5 g (0.16 oz) of KoiCure™ until evenly mixed.
    3. Coat the Food: Place koi pellets in a bowl or bag. Add the medicated gelatin and mix until evenly coated.
    4. Dry: Spread on a tray and air dry for several hours or refrigerate uncovered overnight.
    5. Store: Refrigerate in an airtight container. Use within 7–10 days.

    Feeding Directions:

    • Feed once or twice daily for 10–14 days
    • Feed only what koi will consume in 5–10 minutes
    • Do not feed below 50°F (10°C)
    • Remove uneaten food promptly

    Important Notes:

    • Do not combine with other antibiotics unless directed
    • For bacterial infections only
    • Maintain excellent water quality and aeration
  • Choosing Between NitroCure™, KoiCure™, and KanaRx™

    Q: How do NitroCure™, KoiCure™, and KanaRx™ differ?
    A: All three are pure Aqua Meds antibiotic treatments, but they are used at different stages:

    • NitroCure™ (nitrofurazone) – First-line external bath treatment for most ulcers, fin rot, tail rot, and gill disease. Can be used as a dip, short-term bath, or long-term bath.
    • KoiCure™ (oxolinic acid) – Strong immersion treatment for more serious or persistent external infections, especially those with a gram-negative or septicemia appearance (red streaks, bloody patches).
    • KanaRx™ (kanamycin sulfate) – Deep, broad-spectrum antibiotic for severe, resistant, or internal infections. Can be used as a bath, pond immersion, or medicated food.

    We do not recommend using them at full strength at the same time. Instead, they can be used sequentially (for example: start with NitroCure, step up to KoiCure if needed, and reserve KanaRx for the most advanced cases or internal infections).

    Q: Which one should I use first?
    A: As a simple rule of thumb:

    • For new, straightforward external infections, start with NitroCure™.
    • For more serious or persistent external infections, consider KoiCure™.
    • For severe, resistant, or clearly internal infections, or when you need medicated food, use KanaRx™.
