Just bought one of these. I would like step by step instructions as to how I go about leveling the ground. Intex specifically says NOT to use sand to level the ground. I know that I need to take earth from the high side but am not sure how to go about doing it and making sure it is level. I am prepared to rent a manual sod cutter but in no way want to hire this out. Can anyone help me? Pix would really help!
