We have and 24' ag pool that we put up 3 years ago and have had nothing but trouble keeping the water clear. This year we replaced the liner, filled it up and it had nice clear water. Shocked it (with shock I had left over from last year and kept inside) and it went cloudy. We have added 2.5 cases of shock and it STILL wont hold chlorine. The pool company sold us flocculant and we used as directed and pool water was almost clear, started adding shock again and it went back to being cloudy and still wont hold chlorine. Tired of spending money and getting NO RESULTS. PLEASE HELP!
