10 yrs w/o incident. Crystal clear water, even upon opening. Using 6 way strips, A little ph adjustment, some shock and we were good to go. A couple of weeks after we replaced the liner last year, the pool became progressively cloudy. Whitish up close, light green/yellowish from afar. FC was low, so I'm thinking algae. Tried shocking, but looked like it became worse. Visited several "pool stores" and all readings came back fine. Finally flocked, and things seemed to be back to normal. Opening this year water was brown. Storm punctured a hole in the cover. Shocked and was fine. About a week ago, water became whitish again, FC was low, so here we go again. Began shocking with trichlor, then oxy, and finally bleach. All along, looks to be getting worse. Just used 3x dose of clarifier. Filtering 24/7. My test kit should be here Friday, then I could start BBB for good.
