Koi food should be stored in a cool, dark, dry place where the temperature remains constant. A refrigerator or freezer seems like a good idea. But when you take the food out to scoop some for the Koi every night, the remainder of the food warms up slightly. That warming causes condensation, especially if the food is in a well-sealed, air-tight container. The condensation causes mold and mildew, which can be toxic and poisonous to Koi! Many Koi have become ill or died from Koi food that has been stored in a refrigerator or freezer. The best bet is to store Koi food in a cool, dark, dry place, like up on a shelf in the basement, and to never buy more than you can use in 6 months. One of the most important ingredients for Koi health is the Vitamin C in the food, and even stabilized vitamin C becomes nearly useless after 6 months. High quality Koi pellets from all the major manufacturers are a complete diet that supplies all the nutrients and trace minerals that Koi need to thrive. The Koi diet can be supplemented with fresh vegetables or fruit, but additions should comprise no more than 20% of the total fed.
