>- Not knowing ever you were infected with strongylodies.
This is not what I say. What I say is that you do not know because you have not tried.
If all zappers were the same, then I would not be spending my time researching, designing, developing, manufacturing, and selling the ones that I do.
Each ParaZapper model is distinctly different from anything else out there except the basic ParaZapper STD for $58 .
When I can zap pond water and achieve basically a very close to 100 percent microbial kill rate in just two 1-hour zappings, I have something that no other zapper can claim.
