This Spring, as temperatures begin to rise, your fish are going to become more active and will start coming to the surface looking for food. When water temperatures reach 50 degrees you may begin feeding them wheat germ fish food. We recommend Microbe-Lift Cold Weather Food (Wheat Germ). Wheat Germ is easy to digest at low temperatures, making it perfect for nourishing your fish after a long, cold winter. Place a pond thermometer in your pond to determine the water temperature before you begin feeding. Once water temperatures reach above 65 degrees you can begin a diet of Microbe-Lift Legacy Summer Staple.
