I am using the BBB method for pool balancing. My water was crystal clear last week and balanced well. I didn't test for chlorine for several days and now my pool is getting a little cloudy. I also have a skimmer sock which has some mild algae on there now. Yesterday, the FC was zero and then I shocked it with 50 ounces of bleach (6%). Should I get the FC level to higher than 8? Today, the FC is 1.0. I'm using the Poolmaster 5 way test kit.
