Ok so i have been montoring my pool over the winter months. I live in NC and we have had some cold days and hot days. I closed my pool in October of 09 and now my water lvl is about 7 to 9 inches below the skimmer, is this type of evaporation normal in winter? The cover i have appears that it is not allowoing any water to get back into the pool and i have been pumping it off the pool for the past several months. I am worried that i might have a leak, its so hard to tell because it has been raining and snowing here forever so the ground is wet from the weather. On a side note; looking in my pool i would say that with the BBB method my pool is cleaner closed then most are when they are open. Any help with this would be greatly appreicated. I cant wait to OPEN its killing me!!!!!!
