So I stumbled upon a this idea of a Natural Pool while looking a koi ponds the other day. A Natural Pool is basically a pond with the swimming area of a pool in it that is deep. It is naturally filtered by aquatic plants and harbors wildlife in its shallows. It is configured so that it is one giant bio filter. I know there more popular in Europe and Britain but not so much here in the US.
Does anyone have any experience with this? I was thinking about converting my pool to one(in the very far future), but Internet sources are very limited on the topic? Just want to hear from y'all and see what ideas y'all have.
Heres an image of the natural pool.
Thanks for any information. Mark.
