I agree, why the Grass Carp? I don't recommend stocking them unless you have an underwater weed problem and don't want to manage the problem weeds with herbicides. If there aren't enough weeds in the pond now, they will muddy the water rooting around trying to find something, anything to eat and then trying to get underwater weeds established will be very difficult. Where in Central Indiana? We are about 30 miles S of South Bend.
Do you have spawning habitat in the pond for the different species of fish?
