We used a laser level, within 1.5 inches all way around. had to wait 2 weeks and drain and fill a small area after the Georgia monsoons... ground is hard,hard clay and rocks (we live on side of a Ridge). As the water filled we noticed it was off some , but thought we were within limits...then added pt 2x4 on 3 posts trying to salvage our work...ah... we were so sincere in our working in the 94's and us grandparents Hubby went oot, and I watched it fill and realised as it was almost at top that a leg moved off the block, and it was high on two sides and low on two, like a bow.... so we have been draining it for 2 days Plus skimmer was in high spot. Looks to 4" too high on opposites sides .
We are planning to get level out and respot it. Then dig out the 4 high poles on opp. sides (2 high, then the next two are lower), and perhaps put pavers under the low ones....? We may rotate the pool so skimmer is on one of the low sides. (the low sides are opposites and the high sides are opposites...)We don't want to completely try to move it off of armour pad /tarp as we fear it will damage the bottom.And there are only 2 of us .(we have put up regular above ground pools when we were younger 24ft.).
I will be on my knees with a handpick as yes, the ground is that hard...
open to suggestions...have read where others had some uneveness... it is similiar to a Intex ultra frame
