Ready for water in as little as 10 minutes! Super easy setup, no tools needed! Your pool comes with a cartridge filter pump which allows for a clean swim experience giving the pool faster water circulation and improved filtration. Constructed with triply ply material for puncture-resistant PVC. Please Note: Proper installation of any above-ground pool requires an area, sufficiently larger than the desired pool, to be leveled flat. Uneven ground, hills, or holes must be leveled before pool assembly begins. If severely uneven ground prohibits level ground, proper installation will not be possible.
