Frequently Asked Questions About Pool Electrolysis

What is saltwater electrolysis for pools?: Saltwater electrolysis is a system that uses dissolved salt (NaCl) in the pool and produces chlorine on-site through an electrolysis cell. The pool has mildly salty water (about 3-5 g/L, much less than seawater) and doesn't require manual chlorine addition.
How much does an electrolysis system installation cost?: The initial investment for a quality electrolysis system ranges from €1,000 to €2,500, including the device and installation. Cheaper models exist but typically have shorter cell life and fewer features.
When does switching to electrolysis pay off?: For most private pools, the switch pays off within 2-4 years, depending on pool size and chemical prices in your region. The larger the pool and longer the season, the faster the return on investment.
Is saltwater harmful to pool equipment?: Modern systems maintain a low salt level (3-5 g/L) that is not aggressive toward standard equipment. However, using corrosion-resistant equipment (stainless steel ladders, quality lights) is recommended for maximum lifespan.
How much salt needs to be added to a pool?: For a standard 50 m³ pool, about 150-250 kg of salt is needed at the start of the season. Salt is not consumed — it is recycled through electrolysis. Top-ups are only needed to compensate for water loss (splashing, filter backwashing, rain).
