Lawyers for some of the families affected say the outbreak was the result of "extreme negligence"


that has to be some super extreme negligence, because legionella doesn't thrive in hot chlorinated water.

Hot as in 60 °C (140 °F)? You have it all the time at that temperature? You make sure all pipes and tubes are free of biofilms?

lolwut? temps above 30°C and the presence of chlorine (at least 2ppm, hot tubs should be at 3-5 PPM) and the right pH level (7.2 - 7.8, which is where a hot tub should be) are enough to keep it in check.

This is their optimal growth temperature and depending on how and where you dose the chlorine in there will be spots in your system that are below the conditions that inhibit them. And once they had the chance to form a biofilm then even high concentrations of chlorine won't kill them because it might not reach the cells buried deep in the biofilm.

honestly it really comes down to whether or not you're taking proper care of your tub. you're supposed to shock to about 10ppm once a week.
