This is a short video talking about how to build a fairly simple ecosystem styled pond without spending a lot of money. More information at https://ozponds.com In the video I talked about some other helpful videos, here they are: Bog in a barrel- https://youtu.be/zvoOCq3gcTc High flow filter- https://youtu.be/TMSoMHtL1Ug Designing a bog filter- https://youtu.be/3d_dx0Drn04 DIY Skimmer- https://youtu.be/zfIlRZO3nxI Building an intake bay- https://youtu.be/NSraqlISDDg Pond plants in and around a pond- https://youtu.be/IwnYPZ9HJaQ In the video I mentioned bioballs this is what they are- https://amzn.to/3VmAJ2M (Amazon link) These will provide surface area for beneficial bacteria. These are only used in a high flow filter. In a bog filter the rock and pebble provide the surface area for the bacteria. I also mentioned good quality liner. In my opinion the best liner is EPDM rubber. It's UV stabilised, Stretchy, easy to work with and can easily be repaired if a puncture occurs. https://amzn.to/3PWFoas (Amazon link).
