Our pool is complete and yesterday when I was walking around in the pool I noticed that there was a few rocks under the liner that I could feel in the shallow end. Later that night we turned the lights on in the pool and it appears that there are several rocks under the liner (and decent size ones at that) in the deep end too. Before I call the pool company I want to know if its normal to have a few rocks under your in ground pool's vinyl liner and if so what amount is acceptable? I'm a little frustrated to because our liner also has ripples in it and I was told by the pool company that they will work themselves out over time, which may or may not be true but there are no working rocks out.
