Nothing is more unsightly than a bunch of exposed posts and decking around an above ground pool.
It allows air ciculation, but keeps the 'critters' out for the most part. Consider covering the ground under the deck, between the pool and lattice with polyethylene sheeting, or other appropriate ground cover. It keeps the weeds down to a minimum. We have a 24'round above ground, and are currently building a pressure treated deck around it. Our deck is rectangular 32'wide by 36' out in length away from the existing house deck.
