Pond Boss Forums GENERAL QUESTIONS Muddy water Help Please -Our pond keeps turning brown

200 Triploid Grass Carp is way too many, I'll bet that there is your problem. Ducks can muddy water too, if they are all in one area they can do that. A customer had a pair of white ducks that he let into his pond. The pond was about 3/8 acre. They kept the water muddy and continually washed dirt out of the bank, eating the roots of whatever grew along the banks. Once Coyotes or Hawks/Owl removed the last duck I was amazed at how fast the pond water cleared up.
