Benefits of choosing a saltwater pool

The choice of a saltwater pool has gained significant popularity, both in Sweden and internationally. Many appreciate the pleasant feel of saltwater, while lower maintenance costs make it an attractive option for pool owners.

Before a final decision is made, however, it is of the utmost importance to carefully consider several distinct factors that differentiate a saltwater pool from a conventional freshwater pool.

What is a saltwater pool?

A saltwater pool differs markedly from a swim in the sea, despite its name. The salinity is considerably lower than in seawater, more comparable to the brackish water of the Baltic Sea (approximately 0.4%) than, for example, the Mediterranean Sea's 3.8%.

The advantages of a saltwater pool include a milder chlorine smell and water that feels gentler on the skin and eyes. In addition, saltwater pools usually require less maintenance, are considered more environmentally friendly, and have lower operating costs in the long term. It is, however, important to note that a saltwater pool still requires careful monitoring and ongoing maintenance to ensure clean and fresh water.

How do you clean the water in the pool?

To clean the water in your pool, different methods are used depending on whether you have saltwater or freshwater. A common misconception is that freshwater pools are cleaned with chlorine and saltwater pools with salt. This is not entirely correct, as both are cleaned with chlorine, but the process differs. In a freshwater pool, chlorine is usually added through chlorine tablets or liquid chlorine. In a saltwater pool, chlorine is instead produced with the help of salt and a salt chlorinator. Whether you prefer fresh or salt water in the pool, it is important to always maintain proper pool care.

Even if you clean your pool with chlorine, it is necessary to install a pool pump. This is essential for keeping the water properly clean and clear. The pool pump’s most important function is to pump the water out of the pool, through a filter where it is cleaned, and then pump it back into the pool again. By continuously circulating the water, the risk of algae and bacteria growth is reduced, ensuring an enjoyable swimming experience.

Does a salt chlorinator require a higher water temperature?

A salt chlorinator requires a water temperature above 20 degrees Celsius, as it operates less efficiently in colder water. This means that you may need to use a pool heater to keep the water above 20 degrees, unless it turns out to be an exceptionally warm summer. This is a cost that should be included in the calculations, in addition to the electricity consumption that arises.

Can the pool equipment withstand saltwater?

Naturally, it is crucial that all pool equipment is designed to withstand saltwater. This includes the pump, pump filter, and pool heater, all of which must be compatible with the effects of saltwater. Most modern pool components are designed for this, but it is important to make sure in advance, especially if you plan to convert an existing pool with all the equipment already in place, from freshwater to saltwater.

The salt primarily affects the metal parts in your pool and can lead to rust formation, despite the salinity being very low. Although lights, ladders, and skimmers are made of materials claimed to be rustproof, this is no complete guarantee, as these parts will be affected by corrosion over time. To ensure long-lasting durability, plastic or titanium should be chosen for these components.

Components above the waterline can also be affected, such as the screws in the wooden deck around the pool. These are damaged when they get wet after swimming, which is why it is important to choose materials here that can also withstand saltwater.

Summary

There are unquestionably several aspects to consider before deciding to get a saltwater pool. These range from maintenance and equipment to feel and experience. Below is a list of advantages and disadvantages. Compare these carefully before making a decision about which type of pool you want.

Advantages of a saltwater pool:

• Less chlorine smell: Saltwater pools have a milder chlorine smell compared with freshwater pools.

• Better for skin and eyes: Saltwater is considered gentler on the skin and eyes.

• Less maintenance: Saltwater pools usually require less frequent maintenance than traditional freshwater pools, since the salt chlorinator automatically generates chlorine.

• More even chlorine level: Saltwater pools tend to maintain a more consistent chlorine level over time.

• More environmentally friendly: Chlorine is produced from the salt in saltwater pools through a process similar to what occurs in nature, which is considered healthier and more environmentally friendly.

• Lower operating costs in the long term: Although there may be an initial investment, saltwater pools can lead to lower operating costs over time due to reduced use of chemicals and less need for maintenance.

Disadvantages of a saltwater pool:

• Rust issues: Saltwater can cause corrosion on metal components in and around the pool, requiring the use of corrosion-resistant materials or regular maintenance.

• Installation cost: Initial installation costs for a saltwater pool, including a salt chlorinator and other necessary components, may be higher than for a freshwater pool.

• Higher energy demand: Salt chlorinators may require more energy, especially if the water temperature needs to be kept above a certain level for efficient chlorine production.

• More complex maintenance: Although saltwater pools may require less frequent maintenance, it can be more complicated due to the need to manage salt and the extra equipment required for salt chlorination.

Now it is up to you to choose! Will it be the traditional freshwater pool or the increasingly popular saltwater pool?
