These Instant Easy Clean Duck Ponds have been created using children's pools. There are several different ways to do this. You can simply fill the pool and tip the water out when you want to clean it. Or if you want to make the pond into a more permanent structure you can can build a base. Instead of building a base you could also sink the pool into the ground. For easy draining you can put a hole in the pool and seal it with a plug. Simply remove the plug to drain and put it back in place when you want to refill it. It's important to make sure you have provided enough space for your ducks. You might want to consider using more than one pool if you have a lot of ducks.
