i have been taking care of the pool by myself while my husband is out of town. this is our first year. the chlorine and ph is fine. heater not on yet. we live in mn and it's still cold. but the water is still cloudy. it's a healthy green but not clear. we have been told to just keep running the filter and it will clear up. been a week now that the chemicals have been good. i have been vacumming every day too. how long till it gets clear or do we do something else?
