C is for Chloramines - A to Z Blogging Challenge
​When was the last time you walked into a building or facility that had a swimming pool and you COULDN'T smell it? Has that ever happened to you?

Generally speaking, when there is a swimming pool indoors you will be able to follow your nose to the water. 

Some swimmers feel that the chlorine smell is a good sign - it shows them that the water is clean and sanitized and ready for them to jump in. 

Other swimmers complain that the smell hurts their eyes or noses and worsens their asthma.

Most swimmers don't understand that the chlorine smell in the air is caused by chloramines, and if they did, many of them still wouldn't understand what that really means.

If you own or operate an indoor pool, I am sure you have been searching for a universal solution to chloramines for years. To date, there is no perfect cure, but understanding the causes will help you create solutions to reduce, if not entirely eliminate, the problem.
Chlorine is one of the most common swimming pool sanitizing agent, however there are some common misconceptions about it.  For example, many pool users consider that "chlorine smell" we were talking about to be a sign that the pool is using too much chlorine in their water. 

That is not the case; in fact, it is usually the opposite. Free chlorine in the water kills germs and prevents the spread of waterborne illnesses. It also oxidizes natural wastes from swimmers (sweat, bodily oils, urine, etc). It is only when there is not enough free chlorine in the water to effectively control the natural wastes that the chloramine smells start to really be noticable.
Quote from Professional pool operators of america on chloramines and free chlorine
With all that being said, regardless of how perfectly you maintain your pool water, chloramines will form when people get in the pool and they will “off-gas” into the air surrounding the pool.

This process of "off-gassing" brings us to our title topic - how will a liquid solar pool cover like Heatsavr affect chloramine levels? The easy answer is not at all. 

The more detailed answer is...

Heatsavr - and all other liquid pool covers - work by reducing the amount of evaporation a swimming pool experiences. This, in turn, lowers the amount of heat and water lost from a pool, and will save money because the equipment will not have to run as long or as hard to maintain water temperature and desired humidity levels. 

Knowing this information, some new liquid pool cover begin to wonder if it will prevent the chloramines from off-gassing. 

Heatsavr, as much as we would love it to be, is not a miracle worker. It can only decrease the rate of evaporation by 30 - 40%. This can create incredible savings for a pool owner, but it won't restrict the off-gassing process to any significant degree.

So there you have it - using a liquid pool cover will not affect the chloramine levels in your indoor pool area, either for good or bad. It will, however, provide a myriad of other benefits for you, including reducing your operating costs! If you have any questions that weren't answered here, please leave a comment below!
