I have an AG 16x32 that I'm considering installing a SWG. The company that I've recieved a quote from says they use a system that includes an ozonator due to the fact there some bacteria that are resistant to chlorine and an ozonator will take care of these bacteria if they should ever appear in our pool water. I was wondering if anyone has heard of this?...Argrees or disagrees with this?....any pros or cons to the ozonator? Any truth the the rumor that ozonators afffect asthamatics?

Any information would be helpful. Thanks
