Clearwater D Series Chlorinator Electrode Cell
This Salt Chlorinator manages its own self-cleaning which means you only need to clean the electrodes from time to time.
Despite what you may see in advertisements or what some distributors and manufacturers claim, salt water chlorine generators are not completely maintenance free systems. Your salt water chlorinator requires some regular inspections and service, same as your filtration system and other pool equipment.
One of the things, which need to be inspected, is a level of calcium build-up occurring on the electrodes of your cell. Depending on your water balance and what type of salt water chlorinator you have, this build-up can range from 1-2 mm in a year to 1 cm in 2-4 weeks.
Factors affecting calcium build-up
There are two main factors, which affect the amount of calcium that builds up on your electrolytic cell. One of them is total running time of your chlorinator, another - water chemistry. Running time is simple - the longer the machine runs the greater the amount of calcium that will be deposited on the cell. The chemical balance of your pool water on the other hand is a lot more complex and often overlooked as a cause of excessive calcium build-up. It may not be enough to only check chlorine residuals and PH levels.
