Hi. I have a 15 ft x 48 inch intex metal frame pool. Blue on the outside. So put it up and it was 8 inches off. Had fun swimming in it for 3 days until it leaned to much and am draining the water now. It was a new spot in the yard this year and was not as level as I had thought. I have a 2x4 8 feet long with a level taped to it in order to level spot. once I level spot can I put pressure treated plywood down on top of the newly leveled spot and a tarp over it and the pool on top of that? Can the pool sit on top of plywood? I am not talking about just putting the posts on plywood but the entire pool. I plan then to lift the plywood up end of season...store it...reseed grass and then put it down next year. We only get three months out of the year to swim here so the rest of the months I want grass.
