Legacy High Growth and Energy Growth and energy has added color enhancers and Vitamin C. For feeding 3 days per week. Will not cloud water. In the late spring when the warmer temperatures arrive, koi and goldfish need a boost of protein for growth since they have depleted their fat reserves over the winter. In the fall, a higher protein diet is also required since pond fish need to bulk up in preparation for their winter fast. Use this feed at a minimum temperature of 68-Degree F (20-Degree C). Pond fish really start to grow at this temperature. You can use Legacy Growth and Energy Food up to four times per day. Feed between 2-3-Percent of the fish's body weight per day.
