24 hrs later, & cl is still way high, ph & alk is low. Water looks a tiny bit different shade today. Maybe a lighter green with a tinge of blue tint, but still very cloudy. Should I be vacuuming or something? I feel like I am wasting time by not doing anything. All I have done is backwash. If you even go near the pool, you can smell the cl. What have I done wrong?
