Do some reading on carrying capacity. Most ponds will reach carrying capacity in 2 years as the fish all try to fill up the pond with their own kind. Stocking into a pond that has had fish in it for several years requires managing the fish there to make room and/or increasing the food supply through feeding or fertility (if needed). How do the fish look now fat or skinny ? You may better off spending the money on feed rather than adding more CC.
