Well I need a hand on why my Intex 15x48. Ground was leveled and tamped,perfect. Put up pool,checked,perfect. Filled and kept leveling legs,perfect. Now it's 80% full and liner is off by 1-1/2 squares on one half of the pool? Ran a line level side to side and around,perfectly level. Put level on the water,perfectly level? Pool level, liner not,or am I seeing things? Put up a hard sided pool years ago and that was perfect. Wanted to try the Intex for a few years to see how much my kids use it before investing in a hard side profeshonally installed pool ($$$). What am I missing.
