Pools get cloudy for a number of reasons. This article will discuss several of them, but keep in mind you could have a combination of these factors going on. If you need further guidance, contact us, or request an online training with us.
I have never plastered a pool in my life. In fact, until this week, I had never even seen pool plaster being applied. To be honest, I did not even know the difference between plaster, cement, gunite, concrete, shotcrete, or any other type of -crete. Because of this utter lack of knowledge and experience, I thoroughly enjoyed my time at this year's National Plasterers Council (NPC) annual conference in New Orleans.
Not only is peeing in the pool disgusting, it also results in harmful disinfectant byproducts (DBPs) being off-gassed from the water. Examples of these DBPs are chloramines (specifically the airborne NCl3, Nitrogen Trichloride), chloroform, cyanogen chloride, and other gases. They are harmful and cause swimmers like me to develop asthma and lifeguard lung. Ironically, our urine is one of the root causes of the harmful air we breathe. One would think that would be enough to stop swimmers from peeing in the pool. But there are valid reasons why swimmers pee.
Any pool is capable of having world class water clarity, provided they have the right components and management practices. Most pools face cloudy pool water at least some of the time. In this article, we focus on the pools that consistently have stunning water clarity. What are they doing differently?
As a follow up to part 1 and part 2 of the history of pool indoor air quality (IAQ), I reached out to Keith Coursin, the President of Desert Aire Corp, a prominent pool dehumidifier manufacturer. Coursin has been in the field of HVAC technology since his 20's; in my personal opinion he's one of leading experts on pool dehumidification in the world. This is my interview with Keith Coursin.

Indoor air quality problems are usually equated to chloramine issues. Airborne chloramines are an inevitability with swimming pools, and pool operators alone cannot prevent them entirely. It takes a coordinated effort on both the water side and the air side for healthy indoor air quality to occur. This article is part 1 of explaining the issue.
