Reid Smith wrote on pool use...
In an earlier mention on rifelist you mentioned you had a pool kept
clear with silver electrodes. 
Some interesting info on  http:///www.allworld.com/lifeguard/lgres.htm
This involves copper and silver in pool and bath cleansing.  Many
possibilities here.
New information on copper deficiency in nutrition particularly for men
might suggest some alternative therapy for Lymes?  Copper helps better leg
muscle oxygenation, better ligamental flexibility.
