We just had a company come out and dig down to level our ground. The guy that did it put two piles of sand on top and told us to spread it out and then set up the pool. This is our first pool and I believe we were only supposed to spread it out on the inside of the pool once we set it up. Because of this error, it is about 2 inches unlevel after filling. The pool is an 18 foot oval, steel wall pool and only the ends are unlevel from the sand. Should the sand eventually settle and level out the pool, or will I need to take the whole pool down and restart?
