Thanks, this info helps out some. I did read that ozone is useful only in certain
sytems, but found no mention as to what those systems where. Is the risk
of damage to the whole system worth the benefit this devise brings?? also
what are chances of killin the livestock in the event of a 'part' failure?? Oh and one
more thing, is a ultraviolet sterilizer similar without the harmfull possibility?

thanks,
Shellie
