Just bought the coleman 18x48 steel frame vinyl pool, leveled the ground best I could, added about 1" of sand as a cushion, vinyl protective liner on top of that, then set the pool up....filled pool in about 14 hrs, level is not perfect, about an inch off...no big deal...but here is my issue....the day after filling, we got 2-3 inch rain, really softened the ground and some of my legs are sinking in...no, I didnt use any type of footings as I was afraid as the vinyl liner might expand and rub and cause it to leak or break...so how do I re level, or support these legs without completely starting over...tia
