I was considering buying a zapper. After seeing loads of little things swimming in my blood (not normal) on dark field microscopy, i was wondering if a zappa could rid them? and what about bad bacteria, isn't it necessary to have a few? would i end up killing too many? and what about good bacteria, would i be zapping them too? how do we know exactly what we are targeting and can we be sure that nothing else is getting damaged?
Ta very much!
