Poland_jack i have no visibility at all. I do feed them twice a day. I have limed my pond and sometimes it seems to clear up a little then it rains or its windy and it gets muddy again. I just planted grass around my pond so i hope that will help with the muddy runoff. DIED the redfish was 25 pounds, i have been trying to fish my pond some more but its so windy here it makes it hard to fish.
