Bestway Hydrium 10ft x 48in / 3.00m x 1.20m Pool Set is one of Bestway's range of sturdy steel walled above ground pools. Made with tough, reinforced steel sidewalls for the highest durability possible without the excess weight. To help maintain the quality of the pool water a surface skimmer is included along with a 530 gallon sand filter pump to help remove unwanted bacteria from the water. To allow easy access to the pool a pool ladder is also supplied as part of the package. This is an above ground pool and as a result is not suitable for building into the ground. Pool should be assembled on a solid, zero degree level surface. Adult supervision recommended at all times when children are using pools
