Just a quick video where I talk about how pond filtration works and how it is possible to create a fish pond without a traditional filter, pump or aerator. One thing I didn't mention in the video is fish selection. It is important if you are not going to have water movement that you pick fish that have less oxygen requirements. For example trout come from highly oxygenated environments (running steams) so they need a lot of dissolved oxygen.
If you want to see how any of my ponds or DIY pond filters were built you can scroll through the previous videos and visit ozponds.com
