The Bestway 24' x 12' x 52" Power Steel Rectangular Frame Pool Set is a luxury above-ground pool that has all the fun of a personal pool without all the work and maintenance of an in-ground one. With a soft gray laminated pool liner, brilliant white copings, and a true blue and aqua tile print interior, this pool is a gorgeous addition to your backyard. The steel frame sections lock together easily, while the heavy-duty PVC and polyester side walls keep your pool water and swimmers secure. It's built to last, so you and your family can enjoy years of summer fun. When pool season is over, the flow control drain valve makes emptying the pool a breeze. You can connect it to your garden hose and drain away from your home and distribute the water evenly so you won't ruin your lawn. This pool comes with a filter pump, 52-inch ladder, maintenance kit, repair patch, and an instructional DVD with information on setting up your pool and maintaining it. The included Coleman Filter Cartridge Type IV, Type B is a replacement swimming pool filter cartridge for 2,100 and 2,500 gallons/hour filter pumps. This filter cartridge sifts out the debris and dirt in your above ground swimming pool so the pump can refill it with clean pool water. It's recommended you replace your filter cartridge every few weeks to ensure your pool obtains the highest standard of cleanliness and hygiene. When you maintain your pool's filter, the water in your pool stays attractive and fresh all summer long, which makes it all the more enjoyable for your family and friends.
