Hi all. I'm new to this entire pool thing. So let me start from the beginning. My 6 year old wanted a pool so I thought why not. So I purchased a inflatable ring top pool. Its 12ft around 36 deep. Its nothing spectacular but to her it's a wonderful thing. Also its good practice for me for down the road. The pool I set up on a cement slab in my yard. ( I do have a under pool pad down under it) The slab is not perfectly level maybe 1 1/2 inches off I thought it would be ok. Now I'm not to sure. The pool seems to be shifting or rolling. Im afraid over time it's going to be a real problem. It's only been up a few weeks and its shifted a very noticeable amount. I think I may drain it and put sand down on the slab to level it out. Frame it if I have to. I'm pretty much doing this myself my daughter tries to help .. but like I stated shes 6. So all advice welcome. I don't want to make another mistake. Yet I want to correct this error that I made.
