So I've had my pool for about 3 months now and the last month or so I have very little chlorine at the end of the day. Pool is in sun all day. Pump runs from 9am to 8pm with SWG at 55 percent. This setting had worked great for about a month or so. I have the Tf 100. Results are
Salt 3100 via pool pilot and pool store
I have a dark finish so I can't see anything on the walls and the water is clear, just no chlorine. I have added liquid chlorine occasionally to help. Pulled apart salt cell and it is clean. Even called pool pilot and discussed the volts and amps to the cell which they said was fine. They asked me about phosphates which I had the pool store check and it was at 3000 which is high. I have since lowered to about 300. Just started to slam overnight with chlorinator off. When I went to sleep around 11pm my FC was 20 and cc was 0. When I woke up and checked around 630 FC was 12 and cc was .5.
So something must be in the water correct? What about cc only being .5. I continued to slam and overnight it dropped only 3 points. Am I doing this correct. Almost wish I didn't have the salt cell but the chlorinator that you add the pucks to at the pump.
