Salt or Chlorine Pool: Which is the Best Choice for You?

If you are considering installing an in-ground pool, one of the most important decisions is choosing the type of water treatment. In Quebec, salt and chlorine pools are the two most popular options. Each has its advantages and disadvantages, and the choice will depend on your preferences and budget. Here is a comparison to help you make an informed decision.

Salt Pool

Advantages

• Less chemical maintenance: A salt chlorine generator transforms salt into chlorine, which reduces the need to manually add chemicals.
• Skin and eye comfort: Salt water is softer and causes less irritation for swimmers.
• Less chlorine odor: Unlike traditional pools, chlorine produced by electrolysis is more stable and gives off less odor.
• Reduced long-term cost: Fewer chemical purchases, even if the initial installation is more expensive.

Disadvantages

• Higher initial cost: Installing a salt system is more expensive than a traditional chlorine system.
• Equipment corrosion: Salt can damage certain materials such as natural stone copings,  and is not compatible with copper piping..
• Necessary monitoring: Although chemical maintenance is reduced, salt levels and proper cell operation must still be monitored.

Chlorine pool

Advantages

• More affordable initial cost: The filtration system and chlorine water treatment are less expensive to purchase.
• Effective against bacteria and algae: Chlorine is a powerful disinfectant that keeps the water clean and crystal clear.
• Less risk of corrosion: Unlike salt pools, it is comptaible with copper piping.
• Ease of adjustment: It is easier to quickly change chlorine levels by adding chemicals.

Disadvantages

• More Regular Maintenance: Chlorine levels must be tested and adjusted frequently to maintain balanced water.
• Odor and Irritation: Chlorine can cause skin and eye irritation, in addition to a distinctive odor that can be unpleasant.
• Ongoing Costs: Regularly purchasing chlorine and other chemicals can become a recurring investment over many years.

Which System Should You Choose?

Your choice will depend primarily on your initial budget, the amount of time you are willing to dedicate to maintenance, and your preference for swimming comfort. If you are looking for a gentler solution for your skin and eyes with reduced chemical maintenance, a salt pool is a great option. If you prefer a lower initial cost and quick, effective disinfection, a chlorine pool may be a better fit for you.

Whatever you decide, the important thing is to choose a system that fits your needs and allows you to fully enjoy your in-ground pool!
