The choice of a saltwater pool has gained significant popularity, both in Sweden and internationally. Many appreciate the pleasant feeling of saltwater while the reduced maintenance cost constitutes an attractive alternative for pool owners.
However, before a final decision is made, it is of 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 dip in the sea, despite its name. The salt content is considerably lower than in seawater, more comparable to the brackish water of the Baltic Sea (approximately 0.4%) than, for example, the Mediterranean's 3.8%.
The advantages of a saltwater pool include a milder chlorine smell and the water being perceived as gentler on skin and eyes. Additionally, 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 continuous maintenance to ensure clean and fresh water.
How do you clean the water in the pool?
To clean the water in your pool various 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 accurate as both are cleaned with chlorine, but the process differs. In a freshwater pool, chlorine is usually added through chlorine tablets or chlorine liquid. In a saltwater pool, chlorine is instead produced with the help of salt and a salt chlorinator. Regardless of whether you prefer sweet or salt water in the pool, it is important to always maintain good pool care.
Even if you clean your pool with chlorine, it is necessary to install a pool pump. This is crucial for keeping the water truly 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. By continuously circulating the water, the risk of algae and bacteria growth is reduced, ensuring a pleasant swimming experience.
Does a salt chlorinator require higher water temperature?
A salt chlorinator requires a water temperature of over 20 degrees Celsius, as it functions less efficiently in colder water. This means you may need to use a pool heater to keep the water above 20 degrees, if it doesn't become an exceptionally warm summer. This is a cost that should be included in the calculations, in addition to the electricity consumption that arises.
Can pool equipment tolerate saltwater?
It is of course crucial that all pool equipment is designed to withstand saltwater. This includes the pump, pump filter, and pool heater, which must be compatible with the impact of saltwater. The majority of modern pool components are designed for this, but it is important to ensure this in advance, especially if you plan to convert an existing pool with all equipment already in place, from freshwater to saltwater.
The salt primarily affects the metal parts of your pool and can lead to rust formation, despite the salt content being very low. Even if lamps, ladders, and skimmers are made of materials stated to be stainless, this does not constitute a complete guarantee, as these parts will eventually be affected by corrosion. To ensure long-term durability, plastic or titanium should be chosen for these components.
Even components above the water surface can 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 also choose materials here that tolerate saltwater.
Summary
There are undoubtedly several aspects to consider before deciding to get a saltwater pool. These range from maintenance and equipment to feeling and experience. Below is a list of pros and cons. Compare these carefully before making a decision on what type of pool you want.
Advantages of a saltwater pool:
Less chlorine smell: Saltwater pools have a milder chlorine smell compared to freshwater pools.
Better for skin and eyes: Saltwater is considered gentler on skin and eyes.
Less maintenance: Saltwater pools usually require less frequent maintenance compared to traditional freshwater pools, as the salt chlorinator automatically generates chlorine.
More even chlorine level: Saltwater pools tend to have a more even chlorine level over time.
More environmentally friendly: Chlorine is produced from the salt in saltwater pools through a process similar to that which occurs in nature, which is considered healthier and more environmentally friendly.
Lower operating costs in the long term: Although an initial investment may be required, saltwater pools can lead to lower operating costs in the long term 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, can be higher than for a freshwater pool.
Increased energy needs: Salt chlorinators may require more energy, especially if the water temperature needs to be kept above a certain level for effective 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.
It's now up to you to choose! Will it be the traditional freshwater pool or the increasingly popular saltwater pool?
