What should you do if you recently installed a salt generator on a 35000-gallon inground pool but cannot get free chlorine levels to where they need to be and you also have a white film on top?

The film is from the salt dust and will eventually disapate. What readings are you getting on the salt system. You need to achieve about 3200 I believe. How long is the system running? Needs more run time. Start with 24/7 hrs. until the levels start to rise then cut back gradually. Have you added the required amount of salt? Be careful tho because the formula is not all that accurate.
