The metabolism of koi and goldfish is controlled primarily by
water temperature. When the water cools, fish pond requires less
protein in their diet. When koi and goldfish are fed high-protein
food in cold water, the excess protein is excreted as ammonia
the gills. Microscopic organisms that
biological filter (and consume ammonia) also slow down in cooler
water.
Improper seasonal feeding can lead to an accumulation of toxic substances

survival. When water temperature drops to around
65 ° F, start feeding with Spring & Autumn Pond Food. This type of
Eating fish is better suited for the nutritional needs of the pond

There is no need to worry about "frozen fish" as a part of

may freeze during a harsh winter. Contact your local pool
