I'm in the process of installing a 27' round ABG pool. The pool wall is 52" tall and my liner is a normal non-deep end 48-52" liner. I'm thinking of adding sand to a portion of the pool to bring the depth to 36". Will this work with the current liner and pool or will I have issues with the wall, etc? The pool is a Trevi 207 Steel Wall. Here is a picture of what I would like to do.
