mknauss - one last question (i hope). I think my salt cell is bad. I cleaned it. I have a constant check cell and low salt. I threw in enough salt that it tested at 3.2k. The cell read different. I did the re calibrate procedure. But its slowly falling. Cell is out of sync with my testing again. Would the chlorine level of 10-15 (killing black algae) effect the salt making? Or is it most likely dead. There is flow etc.
