salt chlorinators for swimming pools

Correct sizing requires a minimum rated output of two grams of chlorine per hour for every 10 cubic meters of water, with daily filtration cycles of eight hours in summer.

A 50-cubic-meter residential outdoor pool requires a system capable of producing at least 10 to 12 grams of chlorine per hour to compensate for heat degradation and ultraviolet radiation. In areas with high temperatures or pools with summer thermal covers, it's advisable to add a preventive margin of 20% to the estimated total output.

To accurately check the residual free chlorine and alkalinity levels after starting up the system, it's a good idea to take periodic measurements with the Scuba II Pool Photometer.

Installing a saltwater electrolysis system completely eliminates the pungent odor by continuously breaking down the chloramines that build up in the water.

That irritating smell doesn't come from excess pure chlorine, but from chlorine combining with organic residue, sweat, and cosmetics. Forcing water through the electrolytic cell destroys these combined compounds through direct oxidation.

To ensure a smooth transition without salt deposits forming on the metal electrodes, follow these steps:

• Dissolve special sea salt for pools until the salinity reaches between four and five grams per liter of water.
• Make sure there are no dissolved metals, such as copper, before turning on electrolysis.
• Adjust the pump's recirculation time to allow the full daily water volume to be disinfected during daylight hours.

Preventive maintenance of the titanium cell involves visually inspecting the electrodes every two months and cleaning limescale deposits with mild descaling solutions.

Most modern units have periodic polarity reversal that automatically removes limescale. However, in hard water with a high lime concentration, deposits can build up between the plates and reduce the system’s electrical conductivity.

Never use metal objects, wire brushes, or scrapers to remove residue from the electrodes, as these would remove the ruthenium and iridium oxide coating that catalyzes salt electrolysis. If you need to remove dirt manually before restarting the cycle, rinse with a hose at moderate pressure.

The electrolysis process naturally raises the pH because residual soda is generated alongside chlorine gas, making a regulating pump essential for water stability.

When the pH exceeds 7.6, hypochlorous acid loses more than 50 percent of its active oxidizing capacity, causing cloudiness and algae growth even when the chlorinator is running at full power. To automate this critical control, you can install a Tekna AKL 603 Dosing Pump in the return pipe after the electrolytic injection point.

This automatic system dispenses liquid pH reducer based on the probe reading, protecting the pool against persistent chemical imbalances without requiring daily manual testing.

Saltwater pool chlorinators need an average initial concentration of 4 to 5 kilograms of special salt per cubic meter of water.

For a standard 40-cubic-meter pool, 160 to 200 kilograms of high-purity evaporated salt are required, dissolved evenly before connecting the power supply to the control box. Common salt does not evaporate or get consumed during electrolysis: it recombines in a continuous closed circuit, requiring only small top-ups after filter backwashing or water replacement due to splashing.

It is essential to keep the filtration pump in recirculation mode for twenty-four hours after adding the compound, ensuring it dissolves completely before powering the cell to avoid overheating the internal transformer.

Salt water generated by electrolysis has a salt concentration ten times lower than seawater and is harmless if the metal accessories are made of AISI-316 stainless steel.

If your installation has standard AISI-304 stainless steel components or handrails without a dedicated ground connection, residual galvanic currents may cause surface pitting over time. The risk of corrosion is neutralized by connecting a sacrificial zinc anode to the pipe and maintaining the recommended salinity range.

For automatic cleaning equipment or manual pool cleaners made with technical polymers, the low salinity does not degrade mechanical components or affect the flexibility of suction hoses.

It is possible to apply supplementary chemical treatments in a pool with electrolysis, provided that the active formulations are strictly checked for compatibility with the electrode coatings.

Avoid copper sulfate and algaecides containing heavy metals, as they cause irreversible galvanic deposits on the titanium plates, nullifying their polarity. To eliminate biological blooms without damaging the equipment, apply a technical product such as Algiklean1.1 kg. , Special algaecide for salt electrolysis. by Piscimar.

Also remember the following operating precautions:

• Do not use bromine-based disinfectants in pools with active electrolysis to avoid unwanted residual compounds.
• Keep cyanuric acid or stabilizer below thirty parts per million to avoid blocking its disinfecting capacity.
• Activate the superchlorination function on the chlorinator panel for twelve consecutive hours after a rainstorm.
