Whether you’re looking into your first pool or thinking of switching your existing pool water system, it helps to learn the different types of pool water. You want to know some of the basics as well as the pros and cons of pool water treatment methods. Being well informed makes it easier to make the right choice for your pool.

Types of Pool Water

 

Chlorine Pool Treatment

Chlorine has been the pool water standard for public and private pools over the years. Chlorine treats pool water by reacting with contaminants such as sweat, dirt and urine through a chemical reaction. The reaction results in the breaking down of chlorine into compounds that oxidize bacteria.

Chlorine comes in various forms, such as liquid, tablets, granules and gas. It acts as a residual sanitizer, which means that it remains in the pool at effective levels long after being introduced into the pool.

On the other hand, chlorine creates disinfection byproducts that are commonly associated with dry skin, lung irritation and red eyes. These byproducts also cause the familiar strong odor you’ll find in many indoor pools.

Saltwater Pool Treatment

Contrary to popular belief, salt water systems use chlorine to disinfect pool water, but the source of chlorine is different than that of a traditionally chlorinated pool. This system generates chlorine through the process of electrolysis. The salty water flows across an electrified metal plate that passes a low voltage electrical current through the water. As a result, sodium is removed, and chloride ions turn into chlorine.

The main pros of this treatment method are that the water tends to have a softer feel and swimmers may find the effects of disinfection byproducts to be less noticeable than in traditionally chlorinated water. Saline pools are, therefore, not as harsh on your skin as chlorinated pools. Unlike traditionally chlorinated water, your eyes won’t burn when saline water gets inside them.

On the flip-side, salt water pools can be more corrosive to pool equipment and certain types of stones. These systems will also have higher initial buying and installation costs compared to traditionally chlorinated pools.

Mineral Pool Water

Mineral pool systems use different mineral compositions that have various effects on the water quality as well as on the human body. Mineral pools contain, in addition to essential water balancing chemicals and a sanitizer, naturally occurring minerals aimed at enhancing the quality of water.

Thanks to the health benefits of mineral pool water, there has been a growth in the popularity of mineral pool water sanitization. Typically, minerals such as sodium chloride (salt), Borates, magnesium chloride and Potassium Chloride are included in the pool’s water system for their enhanced benefits.

Borates, for example, create a smooth and silky effect on water and prevents spikes in pH levels. It also lowers the need for chlorine by preventing contaminants such as algae from forming.

Ultimately, choosing the right types of pool water system depends on your needs and preferences. Weigh your options and pick one that best suits your pool. Understanding how each system works makes it easier to make the right choice.
