Just looking through the Intex SWG manual and it states to keep the FC at 0.4-1.5ppm. I am a little confused because I was under the impression that I wanted FC closer to 3? My FC is right on (0.4-1.5ppm) and my PH is right around 7.5, pool is crystal clear. I run the SWG 4 hours a day and the sand pump for 6. I am hesitant to add bleach and try to raise the FC cause my pool is looking so good?
