I am new to the Sws. We have a 14x42 intel pool with the Sws. Just a few days ago the walls became slimy where the sum doesn't hit. I tested the pool today and I have a reading of 0 FC and a PH of 7.2 my salt water level is reading 2260 ppm. The Sws runs for 1 hr and we have boosted it twice! Should I add more salt? Can I add liquid chlorine? Do I add algaecide? I have a three way tester do I need to test something else? No quite sure what to do. I have read so many different things ..... Thanks!
