If you’re considering a swimming pool for your backyard or looking to upgrade your existing setup, you’ve probably come across the growing popularity of saltwater pools. With their reputation for being gentler on skin, easier to maintain, and more cost-effective in the long run, saltwater pools are becoming an excellent choice for many homeowners. But is it easier to maintain a saltwater pool compared to other types? Let’s explore the facts that help you make an informed decision.
What Is a Saltwater Pool and How Does It Work?
Despite the name, a saltwater pool isn’t a miniature ocean. Instead, it uses a process called electrolysis to generate chlorine from dissolved salt in the water. This is done using a salt chlorinator cell, which breaks down the salt molecules and converts them into a mild form of chlorine.
This chlorine sanitises your pool just like traditional liquid or tablet chlorine, but without the harsh smell, skin irritation, or labour-intensive upkeep. You add salt to the pool water, and the system does the rest, continuously producing chlorine while the filter runs.
Here’s a simplified breakdown of how it works:
- Salt is added to your pool and dissolves.
- A salt water chlorinator cell inside your filtration system passes an electric current through the saltwater.
- This produces chlorine gas, which dissolves in the water and sanitises it.
- The process is continuous, as long as the system is turned on and running.
This closed-loop system makes saltwater pools highly efficient and surprisingly hands-off.
Key Benefits of Installing a Saltwater Pool
Choosing a saltwater pool is a wise investment in long-term convenience, comfort, and cost-efficiency. Here are the significant benefits you can expect:
- Gentler on Skin and Eyes: The chlorine generated in a saltwater pool is less concentrated and more stable, which means fewer harsh reactions. Swimmers often report softer skin, reduced irritation, and a more enjoyable overall swimming experience.
- Consistent Sanitation Levels: Since chlorine is produced continuously while the pool pump is running, a chlorinator for swimming pools maintains a more stable chlorine level than manual dosing. This helps prevent bacteria and algae growth before it starts.
- Reduced Chemical Handling: Say goodbye to storing and handling harsh chlorine chemicals. Saltwater pools require far fewer chemical additions, making maintenance safer and more straightforward.
- Lower Long-Term Costs: Once your system is up and running, there’s little need to purchase large quantities of chlorine. The salt water pool chlorinator takes care of it automatically, helping you save on expensive chemical additives over time.
- Environmentally Friendly: Using fewer chemicals means less impact on the environment and your backyard ecosystem.
- Enhanced Comfort: Many swimmers describe the water in a saltwater pool as smoother and more enjoyable, with a reduced strong chlorine smell associated with traditional pools.
- Reduced Odour: The strong “chlorine smell” people associate with pools? That’s often a result of chloramines, byproducts formed when chlorine reacts with contaminants. Saltwater systems produce fewer chloramines, leading to cleaner-smelling water.
Saltwater Pool Maintenance vs. Traditional Chlorine Pools
Sanitation
Saltwater Pools:
Sanitation in a saltwater pool is automated. The salt water pool chlorinator cell generates chlorine on demand, keeping levels steady with minimal intervention. You’ll still need to monitor chlorine levels, but adjustments are infrequent and typically involve adjusting the chlorinator settings rather than adding chemicals manually.
Chlorine Pools:
In a traditional chlorine pool, you’re responsible for adding chlorine tablets or liquid regularly. This means frequent testing and manual adjustments to maintain safe levels. If you miss a dose, chlorine levels can drop, leading to cloudy water or algae growth.
Circulation
Saltwater Pools:
Both pool types require good water circulation to ensure even distribution of sanitiser and prevent stagnant spots. Saltwater systems rely on the same swimming pool pumps and pool filters as traditional pools, so routine checks and cleaning of filters, pumps, and skimmers are essential.
Chlorine Pools:
The process is the same; regular cleaning and maintenance of the circulation system are crucial for both pool types. However, saltwater pools require more attention to metal components, as salt can accelerate corrosion if not correctly managed.
Water Balance
Saltwater Pools:
Maintaining the right water balance is key for any pool. In saltwater pools, you’ll need to monitor:
-
Salt levels (typically between 2,700 and 3,400 ppm)
-
pH levels (ideally 7.2–7.6)
- Alkalinity and calcium hardness
Salt doesn’t evaporate, so once it’s in the pool, you’ll only need to top up after heavy rain, backwashing, or water loss. The automated chlorination process also helps maintain more stable pH and chlorine levels, reducing the frequency of chemical adjustments.
Chlorine Pools:
Chlorine pools require constant vigilance. Every time you add water (from rain or topping up), the chemical balance shifts, often requiring immediate correction. pH swings are common, and chlorine levels can fluctuate rapidly, necessitating more frequent testing and chemical additions.
Basic Upkeep
Saltwater Pools:
- Salt Cell Cleaning: The salt chlorinator cell needs periodic cleaning to remove calcium buildup. This is typically a straightforward process that involves soaking the cell in a mild acid solution every few months.
-
Routine Checks: Regularly check salt levels, inspect the cell for wear, and maintain a clean filtration system. Most tasks are quick and can be scheduled less frequently than with chlorine pools.
Chlorine Pools:
- Chemical Handling: Frequent handling and storage of chlorine products are necessary.
-
Algae Prevention: Chlorine pools are more prone to algae if chlorine levels drop, requiring more frequent brushing, shocking, and vacuuming.
The Role of Self-Cleaning Chlorinators in Simplifying Upkeep
With the availability of a self-cleaning saltwater pool chlorinator, your saltwater pools are designed to minimise manual maintenance even further.
- Automatic Chlorine Generation: The salt water chlorinator cell continuously produces chlorine, keeping the water sanitised without constant attention.
- Self-Cleaning Function: Many advanced models reverse the electrical polarity within the salt cell, preventing calcium buildup and reducing the need for manual cleaning.
- Consistent Water Quality: With a self-cleaning salt water chlorinator cell, you’re less likely to experience fluctuations in chlorine levels, resulting in clearer, healthier water.
- Longevity: Proper care and regular inspection ensure your salt chlorinator cell lasts for years, providing reliable performance and peace of mind.
At Allstar Pool Parts, we stock a wide range of chlorinators for swimming pools, including self-cleaning models that make pool care virtually effortless. Our expert team can help you select the ideal salt chlorinator cell for your setup, ensuring you achieve the best value and performance.
Frequently Asked Questions
Do saltwater pools require less maintenance than pools with chlorine?
Absolutely. Saltwater pools are generally easier to maintain because the salt water pool cell automates the chlorine production process. This means fewer chemical additions, more stable water chemistry, and less time spent testing and adjusting levels. While you still need to clean the salt cell and monitor water balance, the overall workload is significantly reduced compared to traditional chlorine pools.
Can I swim in a saltwater pool every day?
Yes! Saltwater pools are known for their gentle, soothing water, making them perfect for daily swimming. The lower chlorine concentration reduces skin and eye irritation, so you can enjoy your pool as often as you like without discomfort.
Can saltwater pools be used in areas with hard water?
Saltwater pools can be used in areas with hard water, but it’s essential to monitor calcium hardness levels. High calcium levels can lead to scaling on the saltwater chlorinator cell, so regular cleaning and water testing are crucial. Using a high-quality saltwater chlorinator cell and maintaining proper water balance will help prevent issues.
How much salt does a saltwater pool need?
Most saltwater pools require a salt concentration between 2,700 and 3,400 parts per million (ppm). This is about one-tenth the salinity of seawater—just enough for the salt chlorinator cell to generate chlorine efficiently. Once the correct salt level is achieved, you’ll only need to add more after significant water loss due to rain, backwashing, or splashing.
