Hi I am a newbie here and first want to say how amazing this site is. I have learned so much. I am the proud new owner of a 24' by 52" Intex Metal Framed Pool with the included sand filter/pump. I have spent the last three days digging, leveling and then adding sand and finally some blue calm board prior to laying the ground cloth. The weather here today did not cooperate so I am now just stuck at that waiting point. My big question is whether I can safely winterize my pool here in the great frozen tundra state of Minnesota?
