It’s not easy to determine the right amount of food for pond fish. If you ask the fish, you’ll find they’re always hungry.
Scientists can calculate the right amount of food by the size and body weight of koi and others. JBL has printed these calculations as tabular recommendations on the side of the JBL ProPond food bags. Following the amount of grams recommended in the table, you can then use the dosing cup to correctly portion each food type.
