Thanks for the input, Bill.  The water was tested for the presence of
copper (the coils).  However, no detectable amounts were found.  Obviously
no "gunk":-) Doing routine maintenance on an air conditioner one would use
would also help.  Should such fallout be detected in anyone's settup
particularly from a new unit, then adding carbon filtration to the
condensate's sump (pic 3) would eliminate the problem.  

One cannot underestimate the cost savings in less maintenance hassle,
eliminating the cost of D.I. water filter replacement and in providing an
environment that generates sustained overall vibrant fish and plant health.
 I think its worth the effort especially if you have a large aquarium
and/or you aquarium is located where water changing would be most
