I think after you see how well the BG grow using Optimal you will stay with using this brand of food. BG grow really well on this food because of its high digestibility of beneficial protein and low amount of fish waste. Remember when feeding pellets you should be harvesting some of the crop to keep the carrying capacity of total fish biomass balanced for your goals. Harvest is very important for keeping the pond from being overpopulated with too many smaller fish. Annually remove some fish so remaining fish have more to eat and keep growing well on the same amount of food you are feeding.
