Hello experts! New member and first time posting here on the forum! I have a 20k gallon pool that I changed from salt to chlorine shortly after we bought the home about 3 months ago. The deepest part of my pool is 8ft and I have 2 skimmers, 2 bottom drains and 2 side drains. The main pump is a Pentair 4 speed pump and I have a 1.5 HP Pentair that runs the waterfall and a 3rd pump that controls the polaris. The salt cell was dead and had been dead for quite some time so rather than replacing the salt cell I had it switched back to chlorine. I assume that the previous pool company that was maintaining the pool was just dumping salt in to keep the levels where they needed to be. I have a pool company clean and check my levels weekly and backwash every other week. During the day my pool is crystal clear...BUT at night when my pool light is on there are particles suspended underwater EVERYWHERE. Millions of them. My pool company thinks that since the salt cell was bad then electrolysis of the salt was not occurring and I am probably seeing salt particles. They checked for metals in the pool and have ruled that out. Current salt level is 2000 ppm. A photo is attached of what it looks like at night. In the photo, there are a few larger things on the surface that are blurry but the small particles that you can see in the photo are all suspended. My DE filter has been recently checked and the filters removed and cleaned. When I sweep my hands on the steps and sides there is not dust or anything cloudy. Could this just be salt particles left over? Could it be anything else that is treatable without draining my pool and starting over? It really does look gross at night and I am embarrassed to heave people swim when the light is on. I would appreciate some guidance on the issue.
