For example, a small koi pond with a few fish may need water changes every two weeks, while a larger pond with many fish may need water changes every week.


Your koi pond should have a filtration system to keep the water clean, as well as plants and rocks to create a natural environment. Koi fish also need plenty of space to swim, so make sure your pond is large enough.
