Jandy manufactures the AquaPure 700 3-Port Replacement Salt System Cell which utilizes ordinary salt, the electrolytic AquaPure cell generates free chlorine for your pool. As the salt in the water passes through the AquaPure cell, it converts to free chlorine and continuously kills bacteria and algae while maintaining the desired sanitization you need to keep your water pure and clean. When the chlorine is finished purifying the pool water, it converts back into salt and the whole cycle repeats.
