Swimming Ponds

This page is about my chemical-free biologically-filtered low-energy swimming pools. If you don’t want a swimming pool that fish and plants can live in, 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 I’m actually talking about manmade ones).

Here is the introductory article "Turn your swimming pool into a swimming pond" from ReNew magazine.

Here are the detailed do-it-yourself instructions to build the:

Under-gravel filter

Propeller pump

UV-C head

Algae net

Here’s the Yahoo group I started on the subject.
