The heat wave finds Stephan with his beloved ladies. I read in an australian eco mag that 'natural' swimming pools are all the rage, no chlorine, just bio-filtration via vegetation beds to keep the water so low in nutrients that it doesn't get green. Its really really easy to do. Stephan's been doing it for about a decade WITH the extra load of all that nitrogen coming from several big fish fed on high protein food, and its never gone green, nonetheless. A normal swimming pool would not have this nitrogen load. Our filtration volume to pond volume is about one to four though. The bio-filter is filled with shredded hard plastic and reeds absorb some of the nutrients. The walls are very slippery so you have to walk carefully in the pool. One of our friends keeps fish and two boisterous male children in his swimming pool.
