When should I use Medi-Koi®?
Treat with Medi-Koi®, medicated koi fish food:
- when you buy new koi or pond fish to make sure they have no koi, pond fish bacterial infections, always quarantine new koi. Koi Quarantine
- when you open your koi pond in the spring to help your weak koi fight off koi pond fish bacterial infections until their immune system become stronger as your pond water warms up. Note: don’t feed your koi in the spring until your pond water temp reaches 55 degrees F and stays there for one week day and night
