Lydia,

Thanks for that link; that's the guys I'm talking about. There are canals
all over the place around here; my house is not on the water but I'm only
about 300' or so from the nearest canal. I'm not sure if my little 100 gal.
pond is really much of an attraction when there are numerous canals and
swimming pools in the area, but then again I don't know whether its worth
taking the chance. Any pond owners in S. Florida here in this newsgroup?
