To use Nutrafin Max Tropical Fish Flakes, simply open the container using the easy - to - handle dispenser lid. Sprinkle a small amount of flakes into the fish tank, enough for your fish to consume within a few minutes. Feed your tropical fish 2 - 3 times a day. Remember not to overfeed, as this can lead to water pollution and health issues for your fish. Store the container in a cool, dry place to keep the flakes fresh. Make sure the lid is tightly closed after each use to prevent moisture and air from getting in, which could cause the flakes to clump and lose their nutritional value.
