I opened my Pool May 15 2013. I live in Michigan. I refilled the pool with well water as I always do. I ran the filter for 24 hrs and then I put A quart Of HTH Metal Control the pool and ran it for another 24 hrs. I then put 4 bags of Proteam Powermagic AC Superoxidizer. I ran the filter for 36 hrs. I then put a quart of Proteam Prevent Algae control and ran the pool 12 hrs. Water is cloudy and has a light green color to it. I ran the filter at 12hrs for 7 days. I use Proteam 3" Chlorine pucks in an autofeeder. Setting was on three.Test water at pool store,they say shock with 4 bags of SuperOxidizer. Did so ,ran filter 36 hrs straight. Water is clear, but still has the light green color to it.
