So we had a tractor come in and dig a deep end and roughly level the site. I've started fine tuning the leveling by hand checking with a laser level but there was a spot where the tractor went about 1.5" too deep for about 5' of the perimeter. Do I need to bring the entire rest of the pool down 1.5" or can I fill in that spot? In the instruction videos they seem to want it within an inch of level on virgin soil with no backfill. I figured since it's only 1.5" out of level in that spot, even if it settles 40%, I'd still be within their specs. We're supporting all the end posts with pavers and the side posts in cinder blocks covered with concrete.
