I have an Intex 1000 gph EasySet pool pump available. This replaced the original smaller 530 gph pump that came with an Intex 15 x 33 Easy Set Above Ground Swimming Pool. It was used all of 1 year until the inflated ring developed holes and would not longer hold air so we tossed the pool and its been in the garage since getting a rigid frame one instead. Everything works on it, but most if not all of the O-rings are rotted and need replaced on the hosing. If you have an EasySet pool this does a much better job filtering and keeping it clear IMHO the 530 gph included with ours was not enough. Its a nice upgrade if you have the pool already.
