New Pool owner here with question about backfilling abound new pool.

[tomfornow]

Hi everyone, I just had a new sharkline 24x52 pool installed. I have an ecco sand filter with a 1hp motor. My question: my yard was out of level by 29 inches on one end. About 3/4 of the pool in below ground level going from 29 inches in the center to ground level at both ends. What can I do with the area behind the pool walls before it gets to the earth. Can I back fill this area? It is about 1 1/2 feet wide. If I do nothing will the ground erode and fall into the pool walls? Thanks for any help with the problem.

Use something like these:

Lowes retaining wall blocks

Here is a pic of the retaining wall we built behind my pool using basically the same type of blocks that Ben showed above. My yard is also sloped.
