In the last two years, despite a normal appearing cell, normal Intellitouch readings and a good salt level and 8 hrs of operation I always need to add chlorine---
I called manufacturer and the strongly opiniated employee told me that at my gallons the system needs to run much longer and that the cell only lasts 5 yrs so I likely need another one. And that the drip test at the outflow side of the cell is not reliable test of cell function.
I will use this cell as a glorified pump and unplug the control box and manage with liquid chlorine unless someone lead me out of the darkness.
I regret spending the money on this system.
