If you have an old style chlorinator that is not self-cleaning, then, unfortunately yes, but not as often as before. It will now be easier to do so.
If you have a self-cleaning chlorinator, as do most pools, then you should not have to.
Pooled Energy’s Advanced Water Chemistry is less prone to calcium deposits than conventional chemistry, and our use of supplemental magnesium disrupts the crystal structure of calcium deposits making them softer and easier to remove.
Please use the cleaning process recommended by the manufacturer of the chlorinator.
