Pool Water Chemistry
Proper water chemistry (Table 1-2) in swimming pools is critical for the health of the bathers and the condition of
the enclosure and components. An enclosure with poor water chemistry has a noticeable “chlorine” smell, which is
an indication of high chloramine levels in the air. Not only does this have an effect on the water, but it affects the
bathers and the air they breathe.
Dehumidification/ventilation equipment is not designed to remedy the effects of poor pool chemistry, but is designed
to deliver prescribed ventilation to manage smaller amounts of pollutants generated from normal pool activity. Pool
water chemistry is a part of daily maintenance and it is recommended that the users follow the current National Spa
and Pool Institute standards. For more information, see the PoolPak
