Feed your pond fish MICROBE-LIFT/LEGACY Cold Weather Food (WHEAT GERM) during the colder weather periods of spring and fall when nighttime temperatures can go below 55°F (13°C). When pond water temperatures drop, fish require a highly digestible cool-water diet. Our MICROBE-LIFT/LEGACY Cold Weather Food (WHEAT GERM) formula is made with lesser amounts of protein and wheat germ which is easily digested and also contains a higher level of fats.
