Need help quickly! We (4 adults) are in the process of preparing the ground for our 24' Intex pool. so far, we had an excavator come and dig and level the spot due to a significant slope; he added 2 large loads of sand. All day long today we have been leveling the area. We had decided to put 12" patio blocks under the 24 legs - what a huge job that has turned out to be! We've been working for hours, in the heat and humidity, and only have 5 blocks done! We're tempted to stop right there and proceed with the pool assembly. My question is - are the blocks overkill? The instructions don't say anything about the blocks - we only decided to do from reading other posts on this forum. Help!
