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 diet Use this feed at a minimum temperature of 68 degrees F.
Pond fish really start to grow at this temperature. You can use this feed up to four times per day.
