    • Place the unopened bags in your quarantine tank or pond for 20-30 minutes to equalize the temperature.

  6. Avoid Using Shipping Water in Your Tank:
    • Do not add the dirty shipping water to your quarantine tank or pond to prevent contamination.



Setting Up Your Quarantine Tank

Before bringing your new koi home, we recommend you set up a quarantine tank. This helps your koi adapt to its new environment and allows you to monitor it for any signs of illness.

You Will Need:

Koi Quarantine setup
  • A 100-500 gallon tank
  • Net cover for the tank
  • A small pump and filter
  • Salt
  • Pond thermometer
  • Water test kit



    • Ensure good water circulation and an established biological filter. Set up your tank at least a month in advance for the filter to work effectively.



    Acclimating Your Koi

    1. Float the Bag:
      • Place the oxygenated bag with your koi on the surface of the quarantine tank for 20-30 minutes. Cover with a damp towel if in direct sunlight.
    2. Net and Release:
      • Carefully net the koi from the bag and release it into the quarantine tank. Avoid letting any water from the bag into the tank.
    3. Cover the Tank:
      • Immediately cover the tank with a net as koi can be jumpy when stressed.
