| Saratogatan: All things are possible if one is willing to work at it. As DickB points out, a stream is no problem .... if you clean it. Problem is most folks eventually get lazy. In theory, a stream babbling over rocks would add oxygen, nitrification surfaces, de-gassing, etc. ... all the benefits of a Bakki Shower. In practice, every leaf that falls is trapped in the water and rocks, the glarf builds and continuous decomposition sets in. The faster the stream flows, the better. A real torrent will be best .... all the bad stuff gets washed into the pond where the real filters will eventually get it. BUT, if a person takes care to regularly clean it, minimize places where debris will be trapped to rot, etc., then there should be benefits, if they work at it every week. It is all a question of how hard you are willing to work. |
