I finally got my CPSC36 installed yesterday. It ran through the startup process and showed the salt level at 4000ppm. I had already read that this may not be accurate, especially in the first few days of operation. Anyway, the unit showed that it was operating on Polarity 2 which I assume means that it is producing chlorine. I let it run last night starting at 8pm. I checked it this morning around 7:30am and now the water has a foamy white substance floating on top of it. The filter pressure was up from 12psi to about 16psi so I shut off the power since I didn't have time to backwash before work. With the foam on top and increase in pressure does this mean that everything is working and the algae is dying?
