hello! We recently just installed an above ground oval pool ourselves (my husband and a friend who use to professionally install pools) and after filling the pool, I have noticed some separation happened between the wall and an upright at the rounded corner. Is this something that can be adjusted? My husband just deployed, so I’m looking for some reassurance on this, as i’m in freak out mode. Everything else has seemed to be running smoothly with the pool. Attached is a photo.
