You are correct on the size and yes I was aware of the weight when I built the platform. The platform was built because over the 16’ length of the platform there was an 8” drop right to left.

My wife got the pool for free from a friend and wanted it up quickly so while it will have to wait until fall to get prettied up I can assure you it was “engineered” and built properly. The outside is level and I even put on the goggles and put the leave on the bottom of the pool. Checks out there as well.

My main question is how do you get it to fill evenly? I had it filled once and it stood up fine. I drained it to reposition so the filter ports were in a better position and it rolled over during the refill. I must have gotten lucky the first time.

Btw, the overal weight might be 6 tons but the pressure per sq.ft. is roughly 156 lbs. so when building a deck or platform it need s to be able to hold whatever the weight is per sq.ft.
