I live in Wisconsin and that means we can get so brutal winters. I have not covered my above ground pool yet (24' round) and am thinking I may not cover it. I've done all the chemicals, drained some of the water and now it sits. Does it matter if I cover it or not? The cover I have is more like a tarp. We are expecting El Nino this year which means a milder and drier winter for us (hopefully!). What are the consequences of me not covering my pool? <br><br>FYI - I have disconnected the filter and such and stored it.<br><br>Thanks!
