Hello I live in MN and this was our first winter with our above ground pool. We live in a newer development so there are little to no tree's in close proximity to our pool, so we decided to not purchase a winter cover this year. I closed the pool as instructed by the post on this site. This spring when everything thawed the pool looked great, crystal clear. However since we have had an extremely early/warm spring things started to turn a little cloudy as of last Sunday. I decided I would open it this weekend, but it is now turning a little on the green side. I guess my question is when I open it this Saturday do I just fill it up, add bunch of bleach, run the vacuum and let the filter run 24hrs a day while keeping the chlorine levels up at shock level until it clears up?
