permaculture

There was also an article in 'mother earth news' about 4 or 5 months ago 
about natural swimming pools in the article they mentioned that the shallow 
areas heated in the sun light which helped create convection currents which 
circulated water to an extent..

I don't feel that flushing is always necesary if you have the right 
conditions with a balanced ecosystem then the water will remain clean..  


This line of discussion is very close to converging on the topic of 
aquaponics, a very interesting subject for anyone interested in growing fresh 
clean foodefficiently..
