This is something I have been thinking about for quite some time, but I am having trouble researching it. I have heard that oysters, clams, and sponges filter water, but they are sensitive and require specific conditions. Does anyone know of a species that could filter out extremely dirty water and still thrive?
Is there a freshwater animal that could filter, say, a pond into potable water?

Mostly for the purpose of being able to actually drink the water. Or at least get it close. For example, a retention pond would have a lot of runoff from nearby lawns and roads ( in a city area). This would cause a lot of algae to begin to spawn because of the high phosphorus and nitrogen levels, and eventually lead to a dead zone in that area. So, are there any freshwater animals that act as either a water stabilizer so that it does not contain an over amount of nutrients? And are there any freshwater animals that eat bacteria? (Sry for the large question?, just very intrested in seeing if there are any existing creatures that exist as a natural filter.)
Yes, other microorganisms. I think you might benefit from reading here: Aquarium Biofiltration and SwissTropicals Mattenfilter
In essence, you are asking about how waste water is treated. Here is information on that. 3. Wasterwater Treatment See section 3.2.3 Secondary Treatment and section 3.3 Natural Biological Treatment Systems.
