IceShadow was kindly helping but we both thought we were in the clear. That is the reason for new thread. If you read, "help dust everywhere", it will catch you up to this post. I have vacuumed and backwashed several times to get my pool clear. It's been raining and I had virtually no cya. Added 4 lbs with sock method and adjusting alkalinity and pH today. There is no chlorine in pool. Should I add now or wait until dark? When brushing, I felt slimy stuff on walls. Should I do a SLAM or just bring water to shock level? I have algaecide but I also have metals in pool per pool store results so don't want to add more. Unsure of what to do. Water is slightly cloudy after vacuuming but not much. Please help.
