Ok so I am brand new to AGPs and I set up my intex 15x48 this afternoon. I had it as level as I thought I could get it, but now that it is full I am about 2 inces low on one side. I think that the sand settled a bit more than I expected resulting in the 2" difference. Question is do I need to drain and refill? Thanks for any help we were hoping to have some friends over tomorrow for a swim. Here is how it sits, you can see the right side is a little low.
