I have an Intex 48 Intex 18' x 48" Ultra Frame Swimming Pool. 6,423 gal. I am testing with a 3 and 1 test strip and a VUE block. Free chlorine, PH, and alkalinity. I have shocked my pool 3 times. The green water is gone. I have teal cloudy water now. I cant seem to get rid of it. Any information would be great.
