What's confusing? it's just a big bag with a frame to hold it up then you fill it with water



Now I have to sieve the earth (black sand) behind the pool as after all the work that has been done there are a few places that need filled in. At least it is helping in getting the weight down and the muscle tone is getting better, I'm now at 86.4kg, at least it's going in the right direction
The sides of the pool will straighten as the water fills up and pushes them out but they will never be straight.
