Understanding Salt Water Pools
Salt water pools utilize a salt water generator, also known as a salt chlorine generator, to convert salt into chlorine. While these pools still rely on chlorine for sanitation, the process differs from traditional chlorine pools. Instead of adding chlorine tablets or granules, pool grade salt is added to the water. The salt water generator then produces chlorine using this salt, which is continuously recycled and reused to maintain appropriate chlorine levels.
Benefits of Salt Water Pools
- Ease of Use: Adding pool-grade salt is safer and simpler than handling chlorine tablets or granules. Additionally, salt typically needs to be added only at the beginning of the pool season or in case of heavy rain, eliminating the constant need for monitoring and adjusting chlorine levels.
- Gentle and Smooth Water: Salt water pools are known for providing a gentler and silkier water experience. Individuals who may experience irritation in traditional chlorine pools often find salt water pools more comfortable.
- Stable Chlorine Levels: Salt water generators release a steady output of chlorine, ensuring consistent chlorine levels in the pool. This stability reduces the likelihood of problems such as algae growth and cloudy water. Moreover, fewer fluctuations in chlorine levels result in fewer chloramines, which are responsible for the unpleasant chlorine smell.
Drawbacks of Salt Water Pools
- Initial Investment: Converting a chlorine pool to a salt water system can be costly, requiring several thousand dollars for the purchase and installation of a salt water generator.
- Maintenance Complexity: Salt water generators and their salt cells need regular inspection and cleaning. The salt cell may need replacement every three to seven years, incurring additional costs. Furthermore, running the generator requires more electricity, and major repairs or maintenance often necessitate hiring specialized professionals.
- Ongoing Maintenance: Although salt water pools reduce the need for manual chlorine addition, regular maintenance checks and water testing are still necessary. Monitoring pH levels, which tend to drift higher in salt water pools, is crucial to prevent skin irritation, eye burning, and equipment scaling.
- Temperature Limitations: Salt water generators cease to produce chlorine when the water temperature drops below 60 degrees Fahrenheit. In colder climates without a heater, this limitation can affect chlorine production during winter months.
- Corrosion Potential: While salt water exposure is generally not harmful in moderate amounts, excessive exposure can corrode pool fixtures, such as automatic covers, liners, metal equipment, and nearby stonework.
Salt Water vs Chlorine Pools: Which one should I get?
Deciding between a salt water pool and a chlorine pool involves weighing the pros and cons. While salt water pools offer the convenience of reduced chlorine maintenance, a gentler water experience, and stable chlorine levels, they come with an initial investment and ongoing maintenance costs. Monitoring pH levels and potential corrosion are important considerations.
Ultimately, the choice depends on personal preferences and budget constraints.
Saltwater Pool frequently asked questions
What is a saltwater pool?
A saltwater pool is a type of swimming pool that uses a saltwater generator, also known as a salt chlorine generator, to convert salt into chlorine. While it still relies on chlorine for sanitation, the process of adding chlorine differs from traditional chlorine pools. Instead of manually adding chlorine tablets or granules, pool-grade salt is added to the water, and the saltwater generator converts it into chlorine.
How does a saltwater pool work?
In a saltwater pool, the saltwater generator consists of a salt cell and control unit. The salt cell is installed in the pool’s plumbing system, and as water flows through it, an electric charge is applied to the salt in the water. This process, known as electrolysis, converts the salt into chlorine gas. The chlorine gas then dissolves in the water, sanitizing and keeping the pool water clean. The salt in the water is continuously recycled and reused by the generator to maintain proper chlorine levels.
Are saltwater pools chlorine-free?
No, saltwater pools are not chlorine-free. The saltwater generator in a saltwater pool converts salt into chlorine, which is used for sanitation purposes. While the process may be different, saltwater pools still utilize chlorine to keep the water clean and safe for swimming.
Are saltwater pools more expensive than chlorine pools?
Saltwater pools tend to have a higher initial investment compared to traditional chlorine pools. Converting an existing chlorine pool to a saltwater system can cost several thousand dollars, including the purchase and installation of a saltwater generator.
Additionally, there are ongoing maintenance costs associated with saltwater pools, such as inspecting and cleaning the salt cell and replacing it every few years. However, the long-term costs of purchasing and adding chlorine tablets or granules to a chlorine pool can also add up.
Can saltwater pools damage pool equipment?
While saltwater exposure is generally not harmful in moderate amounts, excessive exposure to saltwater can potentially corrode certain pool equipment and materials. Automatic pool covers, pool liners, metal pool equipment, and even natural stonework near the pool can start to erode over time with prolonged saltwater exposure. Proper maintenance and monitoring can help mitigate this risk.
