I was trying to stay away from the pumps everyone I have seen tend to be expensive but it may have to come to that my mom was talking about getting like Lilly pads and certain fish
I have a small man dug pond that my ducks swim in but it stays muddy what can I use to easily clear the mud up that is easily accessible and fairly cheap?
Also how big does the pond need to be to keep fish alive enough for the ducks without having to have an air filter thing?
