I have designed and started a natural swimming pool for my house. For those not familiar with the concept, the basic idea is to make a swimming area free of chemicals that cleans itself using low energy natural processes.
Oxygen is circulated with a low power air compressor to areas in the pool to promote growth of good microorganisms and plants. The plants then out compete the algae for phosphorus - one of the building blocks for most living things.
The concept has been around for years and people are now getting into the action in North America - no harsh chlorine, no additives - natural swimming at its best!
I will update as I go - much work needs to be done before Fall closes in on me!
Here is a sample of pictures of the transformation so far.
