I have built and rebuilt the little water fall and here is what it looks like now. My issue is it is not stable and racoons love to "adjust" it. I want to put in something that is sturdier and can do some bio. filtering as well.

But I can't quite figure out how it could be installed in my pond. I need to redo it and perhaps some foam is my best option. A filter in the pond would work but would be a pain to clean.
