    Re: CDC Hot Tub Advice

    Ok, so we should panic over a report of 16 incidents reported to the CDC in a 1 year calendar period with probably millions of operating hot tubs, many of which are poorly balanced? Personally I feel safe in my hot tub, I test the chlorine and pH before each use, have an SWG, an Ozonator, and a Nature2 mineral cartridge (admittedly the cartridge is not changed on a regular schedule)
    Indoor 20x40 35,000 gallon vinyl pool with 1.5 HP 2 speed Jandy FloPro pump, Hayward EC75 Perflex DE filter, 11 4x12 Techno-Solis solar panels w/ Aquasolar controller, Aquabot Turbo T Robot Cleaner. Also LMI metering chlorine dispenser pump and HotSpring Jetsetter

    There are way more than 16 incidents of hot tub rash/itch/lung in a year. Most residential incidents do not get reported to the CDC. This isn't the same as reporting from commercial/public pools nor reporting of more serious diseases. Just on one spa forum alone I accumulated a dozen or more such incidents. The most common cause was using too little or no chlorine (sometimes due to use of "alternative" sanitizers, which really weren't). Use of Dichlor-only building up CYA over months may also be a cause but there were too few of those incidents to be sure.

    Properly chlorinating with the Dichlor-then-bleach method has not led to reports of these problems and its been a few years now since that was started.

    I wonder how many monitor and change out the water on a regular basis which very important with the high temps found in a spa.
    44,000 gallon, Plaster pool, Hayward C4025 cartridge filter, 5hp pump, Geothermal heated to 87, Chlorine, with Rain curtain feature that has its own 5hp variable speed pump. A Detached Plaster Spa, 650 gallon, C1750 cartridge filter, Geothermal heated to 103, Both are IG but on the 4th Floor, the Equipment rooms are located on 3rd floor.
