At the beginning of the season, add common salt to the pool.
As the salt passes through the chlorinator it is transformed into sodium and chlorine.
Chlorine cleans the water, removing harmful bacteria, and keeps algae and other contaminants under control.
Chlorine to Salt
After cleaning the water, the natural chlorine subsides and reforms as salt. Then the cycle repeats itself, providing a constant level of cleanliness and clarity with minimal effort on your part.
Chlorine is the safest and most effective way to clean pool water. That’s why both chemical and saltwater chlorination systems use it. However, there is a significant difference between the systems.
With chemical systems, concentrated chlorine is added to the pool in the form of liquid or tablets. With saltwater chlorinators, chlorine is produced as part of a natural reaction between salt and the chlorinator. It’s the same chlorine, only it’s produced regularly in a stable, ongoing process, which allows for more consistent chlorine levels, which makes for more comfortable swimming.
Once the chlorine has cleaned the water, it transforms back to salt and the process repeats itself. Because it’s largely self-sustaining, the process requires less work and maintenance than traditional systems.
Typically, once salt is added at the beginning of the season, there is little required, but monitoring the water and adding some more salt or chemicals if needed.
Saltwater Chlorinator Reactions
Overall, salt and water will produce sodium hypochlorite and hypochlorous acid when electricity is added to the chlorinator. Essentially, reactions one and two are mixing together in the pool water and immediately form the disinfectant in the overall reaction.
|Overall Reaction:||NaCl + H2O + electricity → NaOCl (disinfectant) + H2|
|Reaction 1:||2Cl- - 2e- → Cl2|
|Reaction 2:||2H2O + 2e- → H2 + 2OH-|
