The filter cartridge would have to be cleaned on a regular interval for the best of results. And the time discipline of the cleaning is critical. If your hot tub (ג׳קוזי) experiences heavy usage then you would want to clean the cartridge once in a week or ten days. In case of lesser use, the cleaning ought to happen around once in a fortnight.
You would want to use good-quality cleaners for cleaning your Jacuzzi filter cartridge. There are chemicals available that act like muriatic acid but are more effective in removing calcium layers. There are cleaning substances that would have to be sprayed on the cartridge and then it would require further rinsing.
Once you clean the cartridge, you would want it to dry off completely before next use. In case you foresee using your Jacuzzi (בריכות ספא) while your cartridge is still drying, you may want to keep an additional cartridge at home.
