So we got our first pool this year after spending weeks getting everything ready and and levelling out we started to fill it, it's about half way full now and we have noticed a puddle of water at the of the pool by one of the corners. We have mopped it up a few times and it keeps coming back and it is also wet under the pool in that corner, so we figured it must be a leak. We are just unsure of how to find the hole to patch it up, also we are worried it might be leaking from the seam as we needed to move it to level out some more so we moved it with some water in as we couldn't get the last little bit out (it wasn't even an inch of water though)
