I have a unique pool. It appears to be an above ground pool, sunken into the ground, so its more like an inground pool. Around the pool is a deck (my whole back yard) and below the deck is a wood frame and dirt surrounding the whole pool. All of my pipes are under ground. So it is essentially an inground pool (but what do i know!!) Do I need air pillows for my pool in order to close? I need to figure this out asap because I have pool closers coming on Saturday and I dont have any right now! Any help would be much appreciated!
