Table 1-2. Recommended Pool Water Chemistry
Pool Water Chemistry
Water chemistry 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 chloramines in the air. Not only does this have an effect on the water, but it affects the bathers and the air
they breathe.
Dehumidification systems are not designed to remove the effects of incorrect pool water chemistry.
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, review the Controlling Chloramines with Proper Chlorine Management chapter in the
Indoor Pool Water Chemistry publication at the online
