Salt for pools: a gentle and effective way to disinfect your pool.

Swimming in saltwater sounds like pure luxury, and with today's modern techniques, it's also practically feasible. More and more pool owners are opting for a salt electrolysis system instead of traditional chlorine treatment. However, what many forget is that the quality of the pool salt used plays a crucial role.

In this blog, we explain why pure pool salt is important, how salt electrolysis works, and which products are best to use for a crystal-clear and skin-friendly pool.

How does salt electrolysis work in pools?

Salt electrolysis is a technique in which a small amount of salt is dissolved in the pool water. This salty water passes through an electrolysis cell that converts the salt (NaCl) into natural chlorine gas (Cl₂). The chlorine then kills bacteria and algae in your pool.

The big difference with traditional chlorine tablets or liquid chlorine? You don't have to add any chemical products. The system generates the right amount of disinfectant itself based on the salt present.

Benefits of salt treatment in pools.

Switching to salt electrolysis offers numerous benefits, both for you and your pool:

• ✅ Gentler on the skin and eyes – No more red eyes or itching after swimming.
• ✅ No chlorine smell – The typical, pungent chlorine odor is a thing of the past.
• ✅ Lower long-term maintenance costs – No need to purchase chlorine products.
• ✅ Consistent water quality – The system doses automatically, so fewer fluctuations.
• ✅ More environmentally friendly – Less transport and storage of chemical products.

Especially for families with children or people with sensitive skin, this is a smart and comfortable choice.

The importance of pure pool salt.

Not all salt is suitable for your pool. If you use salt with additives, anti-caking agents, or too many impurities, you risk:

• Contamination of your electrolysis cell
• Deposits on pool walls
• Poor performance of your system
• Higher consumption and wear of components

Therefore, it is essential to choose specially developed pool salt, with a purity of at least 99.9% and without additives such as iodine or anti-caking agents.

How much salt do you need?

Most salt electrolysis systems operate with a salt concentration of 4 to 6 grams per liter of water. For a pool of 50,000 liters (50 m³), you will need approximately 200 to 300 kg of salt for the initial start-up. After that, you only need to top up when you refresh the water.

Always check the recommendations of the manufacturer of your electrolysis system.

Conclusion: choose quality consciously.

Pool salt is more than just "salt." The purity and composition determine whether your salt electrolysis system works optimally – and whether you enjoy clear, soft, and odorless swimming water. Therefore, invest in certified products such as POOLSEL® or SOFT-SEL® PLUSS, and avoid long-term issues.
