Pond Boss Forums GENERAL QUESTIONS Muddy water Mallards and My Pond

My neighbor has a 1/4 ac pond and he thought it would be cute to have a pair of white mallards on the pond. He rethought the idea when his banks showed signs of erosion where the ducks were digging in the bank, and his water was constantly turbulent. It's amazing how fast the water cleared up without the ducks (and that's having 100 CC in the pond as well!). There is still a line in the grass at the water's edge where the ducks dug all the way around the pond.
