Since we are moving our pool we are starting over on leveling the ground. Tedious, and summer may well be done by the time we are but I wanted opinions on how people have leveled their ground. Does anyone suggest a laser level, water level etc? Our last setup was about 2 inches off and that was using a standard bubble level and a 2 x 4. Which I would like something more accurate this time around. Also, another question. When you use patio blocks under the legs, these should be under the tarp or on top of it? Or lift up the tarp at each leg and sit it directly on the block? Any advice and help would be greatly appreciated!
