This is my second year putting up pool. I got the pool at the end of summer and used it for about a month. I tried leveling the ground and it wasn't leveled. It did good for the remainder of summer. This year I decided to move it a little so it would be more leveled. Unfortunately it's still unleveled about 3 inches at 2 poles. I also noticed the pool creaks when someone is in it. Should I try leveling ground again and put pavers under pool?
