When deciding on a sanitation system for your pool, the debate is usually between chlorine and saltwater. It’s not an easy decision either, you’re talking maintenance, health impacts and costs into consideration. 

But pools are supposed to be fun and a way to relieve stress, not encourage it, so this guide will explore the differences between Chlorine and Saltwater Pools. By the end you’ll be able to decide what’s right for your home, and start swimming sooner, rather than later. 


Chlorine was invented in 1774, it’s the original means of sanitation for pool systems. It’s also one of the cheapest systems to install and maintain. 


  • Minimal investment and maintenance costs.
  • Require less electricity than most pool systems, which reduces ongoing expenses.
  • Fixture friendly.
  • All pool and repair companies are able to fix chlorine systems, in fact, many repairs can be done by the homeowner.


  • Can be harsh on the skin, eyes, and hair.
  • Chlorine can also be harmful to swimsuits, towels, and pool decks. 
  • Requires constant supervision to kill excess bacteria. You’ll need to test and adjust the chemicals a couple of times per week. 
  • Can be difficult to store. Many homeowners dedicate a specific area, to safely store chlorine containers. 


The biggest misconception about saltwater pools is that they stay clean because they’re the same water as the ocean. You should know that pool saltwater is very different from sea saltwater and also includes a small amount of chlorine.  


  • The chlorine levels are minimal, so it’s much less likely to damage bathing suits and the surrounding pool deck. 
  • Limited amount of overall chemicals, making the water more tolerable and enjoyable for everyone. 
  • Doesn’t require as much supervision or maintenance as chlorine systems.


  • More expensive than other options, especially chlorine. Not only is the initial investment pricier, but maintenance costs as well. 
  • A saltwater pool system is complicated, all repairs will need to be done by a licensed and specialized technician.
  • Saltwater might not damage your bathing suits or hair, but it can cause damage to other components. Underwater lighting, for example, fixtures, liners, even the heater will all wear out quicker with saltwater. 


  • BROMINE: Pool bromine is an algaecide, oxidizer and sanitizer in one. It doesn’t have a strong smell and is gentler on eyes, skin and bathing suits. It can be an expensive system to set up and maintain and due to lack of stabilizer, bromine is more susceptible to sunlight.   
  • UV: UV systems work by rushing the pool water over a UV lamp, that eliminates the bacteria. Unfortunately, it’s not 100% successful, it also doesn’t oxidize the water. Oxidation is an important process that eliminates non-living substances such as metals and bather waste. 
  • OZONE: O3 gasses are injected into the pool’s plumbing in an ozone pool system. They generate energy that breaks down oxygen molecules, producing a chemical reaction, however, it also creates a toxic gas that can accumulate under pool covers or in pump houses.
