Well got my AGP installed today and it is filling as I type. The bad news is they had to dig about a foot down near my deck which means I have a foot drop in elevation from the marble chips under my deck to the pool bottom on one side of the pool. What are my options here? I was thinking about taking out more dirt and building a little retain wall.

How far can I back fill with dirt or stone from the bottom of the pool?

Did anyone else on the forum have this issue? If so what did you do?
