Having a swimming pool in your backyard is a dream for many, offering a perfect place to relax and have fun with family and friends. However, keeping the pool clean and safe is essential, and pool owners must choose a system to sanitize the water. Two of the most popular methods for pool sanitation are saltwater and chlorine. While both work to keep the water clean, they do so in different ways, and each type has its advantages and disadvantages.
In this article, we will explain the key differences between saltwater and chlorine pools, highlighting the pros and cons of each. By the end, you’ll be able to decide which pool system best fits you.
What Is A saltwater pool?
Saltwater pools are a popular option for those looking for a more “natural” way to sanitize pool water. Although saltwater pools use less chlorine than traditional pools, they still rely on chlorine to disinfect the water. Instead of adding chlorine directly to the water, saltwater pools use a device called a salt chlorine generator to convert salt into chlorine through a process called electrolysis.
In a saltwater pool, you add salt to the water, usually in the form of sodium chloride. The generator then turns the salt into chlorine, which is spread throughout the pool to kill bacteria and other harmful organisms. Saltwater pools tend to have lower chlorine levels than traditional chlorine pools, but they still keep the water clean and safe.
Pros of Saltwater Pools
1. Softer Water
Saltwater pools generally have softer water compared to chlorine pools. Because the chlorine is generated by the system, the water feels smoother and more comfortable. Many swimmers find saltwater gentler on their skin and eyes, making the experience more enjoyable.
2. Lower Chlorine Levels
Saltwater pools have a more stable chlorine level because the generator produces chlorine consistently. This means fewer chlorine fluctuations, which helps avoid strong chlorine smells and irritation. In a chlorine pool, the chlorine levels can often change and need more frequent adjustments.
3. Lower Maintenance Costs Over Time
While installing a saltwater pool may be more expensive upfront because of the salt chlorine generator, the long-term maintenance costs tend to be lower. You won’t need to buy chlorine tablets or liquid as often, which saves money over time. The salt chlorine generator can last for several years before needing replacement, and the salt levels in the pool stay fairly constant.
4. Less Handling of Chemicals
Saltwater pools require less handling of chemicals. The chlorine generator does most of the work, meaning you won’t have to deal with potentially dangerous chemicals like liquid chlorine or chlorine tablets. This makes pool maintenance easier and safer.
5. Environmentally Friendly
Saltwater pools are considered more environmentally friendly than chlorine pools because they use fewer chemicals. While they still use some chemicals, the use of salt instead of chlorine reduces the need for producing, shipping, and disposing of chemical products. Saltwater systems can also be less harmful to the environment when used correctly.
Cons of Saltwater Pools
1. Higher Initial Installation Costs
One of the biggest disadvantages of a saltwater pool is the initial cost. Installing a saltwater pool requires purchasing a chlorine generator, which can cost between $1,500 and $3,000 or more, depending on the pool’s size. This is more expensive than the setup for a traditional chlorine pool.
2. Salt Corrosion
Salt can be corrosive to certain parts of the pool, such as metal ladders, handrails, and heaters. Over time, saltwater may damage these components, leading to expensive repairs or replacements.
3. More Complex Maintenance
Although saltwater pools need less chemical handling, they still require some maintenance. The salt chlorine generator needs to be cleaned and maintained regularly, and the salt levels in the pool must be checked and adjusted from time to time.
4. Electricity Costs
Saltwater pools need an electric generator to create the chlorine from salt. This means your electricity bills may be higher compared to a traditional chlorine pool, especially if you have a large pool or if the generator runs continuously.
What Is A chlorine pool?
Traditional chlorine pools use chlorine to sanitize the water. Pool owners add chlorine in the form of tablets, liquid, or granular powder. This chlorine kills bacteria and keeps the water safe for swimming. In chlorine pools, it’s important to regularly check and adjust the water’s chemical balance to ensure the right amount of chlorine is in the pool.
Chlorine pools don’t need a generator or a salt system. Instead, you directly add the chlorine to the pool as needed, depending on the size of the pool, the water’s chemical balance, and the pool’s usage.
Pros of Chlorine Pools
1. Lower Initial Cost
Chlorine pools are usually less expensive to set up than saltwater pools because they don’t require a salt chlorine generator. The pool’s filtration and sanitizing system is simpler, and the overall cost of installation is often lower.
2. Simple System
Traditional chlorine pools are easy to understand and maintain. The process of adding chlorine is straightforward, and you have direct control over the chemical balance of your pool. A chlorine pool might be a good choice if you prefer a hands-on approach to pool care.
3. Easier to Maintain in Some Cases
For some pool owners, chlorine pools are easier to maintain. The system is simple and doesn’t require the special equipment found in saltwater pools. While it’s still necessary to monitor the chemical balance regularly, it’s a straightforward process.
4. No Risk of Salt Corrosion
Unlike saltwater pools, chlorine pools don’t have the risk of salt corrosion. Since they don’t use salt to create chlorine, the pool’s equipment and surfaces won’t suffer from salt-related damage.
Cons of Chlorine Pools
1. Higher Chemical Usage
In a chlorine pool, you will need to add chlorine regularly to maintain proper sanitation. This can add up over time, especially if you have a large pool. The cost of chlorine tablets or liquid can be significant, making chlorine pools more expensive to maintain in the long run.
2. Harsh on Skin and Eyes
Chlorine pools can be harsh on swimmers’ skin, eyes, and hair. The strong smell of chlorine can also be off-putting for some people. If you have sensitive skin, you may experience irritation after swimming in a chlorinated pool.
3. Inconsistent Chlorine Levels
Maintaining the right amount of chlorine in a traditional pool can be challenging. Too much chlorine can irritate, while too little can lead to unsanitary water. Pool owners need to regularly check the water’s chemical balance to avoid problems.
4. Possible Pool Surface Damage
If the chlorine levels aren’t carefully managed, they can damage the pool’s surfaces. Over-chlorination can cause the pool’s liner or tiles to fade, crack, or break down over time, leading to costly repairs.
Final Thoughts
Choosing between a saltwater pool and a chlorine pool depends on your priorities, budget, and personal preferences. Saltwater pools offer smoother, more comfortable water, lower maintenance costs in the long run, and are easier on the skin and eyes. However, they come with a higher upfront cost and can cause salt-related damage to the pool over time. Chlorine pools are more affordable to set up and easier to manage, but they require more frequent chemical handling and can be harsher on swimmers’ skin.
