Chemicals in modern pools can be harsh and expensive.  I designed this pool to include a 36’ lap lane bordered by bog gardens and a waterfall.  With the water being pumped from the cool deep end and into the bog gardens the temperature was regulated.  As the water filters thought the natural plants in the bogs the water becomes naturally clear.  We continued to be amazed at how clear and simple the system was.  All in a spectacular setting of nature.
