Last week we got a good shower everyday, my pond is still filling up. I have about 5-6 feet to go and it will be full my pond is an acre and its about 25-35 feet deep in spots with some shallow spots 3-5 feet deep. I do aerate at night, when i stocked the 50 cc i also put in 500 bluegill and some minnows and this is the first fish i have seen dead since stocking.
