Saltwater pools continue to gain in popularity, but do you know the truth about their pros and cons? In this blog we tackle 5 of the largest myths our clients ask us about saltwater pools.
1. Do Saltwater Pools Use Chlorine? Understanding the Truth
Fact: Saltwater pools do use chlorine, but they generate it differently.
Many people believe that saltwater pools are chlorine-free. These systems produce chlorine naturally through electrolysis. Salt dissolved in pool water interacts with a salt chlorine generator, which uses electrical currents to convert salt into chlorine. This process effectively sanitizes the pool water, just like in traditional chlorine pools.
The main difference is how the chlorine is added. Unlike traditional pools that require manual chlorine addition, saltwater pools continuously generate chlorine at lower levels. This creates a gentler and more stable concentration, reducing irritation for swimmers.
2. Are Saltwater Pools Maintenance-Free?
Fact: Saltwater pools require regular maintenance, and saltwater can be harsh on equipment.
Although saltwater systems automatically produce chlorine, they are not maintenance-free. Regular testing for pH, alkalinity, and calcium hardness is essential. Salt cells within the chlorine generator also need periodic cleaning to prevent calcium buildup, which can impair chlorine production. Salt cell generators typically only carry a 1-year warranty and they are notorious for needing to be replaced within a few years.
Additionally, it is inherently more corrosive than traditional chlorine systems. Over time, the salt can wear down metal components like ladders, rails, and heaters. For example, gas heaters often include internal or external bypasses to reduce the flow of saltwater through the heat exchanger when not in use. This prevents unnecessary exposure to the corrosive effects of saltwater, helping to preserve the heater’s lifespan.
Saltwater pools also require chemicals like muriatic acid to control pH levels, as these systems tend to cause pH to rise over time. While they reduce the need for frequent chlorine additions, they still demand attention to ensure the water and equipment remain in excellent condition.
3. Are Saltwater Pools Gentle on Equipment and Materials?
Fact: Saltwater can be more corrosive to some equipment and materials, but proper management mitigates this.
Saltwater pools are easier on the skin but tougher on certain pool components. Gas heaters often include internal or external bypasses to reduce the exposure of heat exchangers to corrosive saltwater when not in use. This design helps extend the life of the heater.
Natural stone coping, such as limestone or soft flagstone, can degrade faster in saltwater pools. Salt penetrates porous surfaces, causing erosion and discoloration, particularly in hot climates. To counteract this, homeowners can apply sealants, use salt-resistant materials, and rinse surfaces with fresh water to preserve their appearance. Natural stones such as travertine and marble are susceptible to salt water whereas porcelain pavers are impervious to water of any kind, making them a great choice for coping or patios.
Most pool equipment manufacturers provide only a one-year warranty for components used in saltwater systems due to the increased risk of corrosion. Regular maintenance and selecting durable materials designed for saltwater exposure help reduce repair costs and prolong equipment life.
4. Is Saltwater Pool Water Like the Ocean?
Fact: Saltwater pools contain a fraction of the salt found in seawater.
Some people expect saltwater pools to taste or smell like the ocean. But the salt levels in these pools are much lower. However, they typically contain 2,500-3,500 parts per million (ppm) of salt, significantly less than seawater’s 35,000 ppm. This is even lower than the salt concentration of human tears.
Because of this low salt level, saltwater pools don’t have a noticeable salty taste or smell. The lower concentration makes them gentler on skin and hair, avoiding the dehydrating effects associated with ocean water.
5. Do Saltwater Pools Eliminate the Need for Other Chemicals?
Fact: Saltwater pools Still need additional chemicals for balance.
While saltwater pools reduce the need for chlorine tablets, they still require chemical care which is necessary for water balance. Muriatic acid is often required to manage pH levels. You might also need occasional pool shock treatments to remove organic contaminants. Algaecides and clarifiers can help keep the water clear and algae-free.
Testing for pH, alkalinity, and calcium hardness is crucial to maintaining a safe and comfortable swimming environment. Proper care ensures the pool operates efficiently and prolongs the life of the salt chlorine generator.
Additional Considerations:
- Higher Initial Costs: Saltwater pool systems have a higher upfront cost due to the salt chlorine generator. However, the long-term savings on chlorine purchases can offset this expense.
- Generator Maintenance: Salt chlorine generators require periodic cleaning and replacement every 3-5 years. Regular maintenance ensures consistent chlorine production and extends the equipment’s lifespan.
- Improved Comfort: Many swimmers find saltwater pools more comfortable, reporting less skin and eye irritation compared to traditionally chlorinated pools. This makes them a great choice for families with children or individuals with sensitive skin.
Conclusion: Making an Informed Choice for Your Backyard Oasis
