DIY Waterfall pond filter| The Build

This video shows how i built a waterfall filter for a stream I'm adding to my large dream pond. A waterfall filter needs to be able to move large volumes of water through. At the same time we want to incorporate surfaces that can be colonised by good bacterias, trap sediments and be easily maintained. I think this design achieves those goals. But feel free to make modifications.This filter should work in much the same way as an expensive professional waterfall filter.  

Here a video where I used this filter as the headwaters of the stream- DIY Stream, Creek| Dream pond build
