thanks for the help. with 20 - 30lbs for 3 acres it should be borderline for the number needed for the pond. It is at least enough to get a result anyway.

I love having them. they are so light colored that I can watch many of them from the dock. Some hang out alone and some in schools of 10-15.

It has been such a warm spring in eastern NC that some have already started making beds and have devoloped bright red colors on their fins.
