This group is for exchange of information regarding chemical-free biologically-filtered low-energy swimming pools. If fish and plants can't live in your desired swimming pool, then you've come to the wrong place.
These are sometimes called swimming ponds, people ponds, non-toxic swimming pools, green swimming pools, or "natural" swimming pools (although we're actually talking about manmade ones).
We are swimming pond designers, builders, users and dreamers. Let's tell each other what we've done, or are thinking of doing, problems we've had (or are still having) and solutions we've found, ... and how much fun they are.
Here are the detailed do-it-yourself instructions to build the:
Under-gravel filter and a drawing
Power supply and control box (instructions not yet available)
