I've been looking and found some great end of summer pool deals. I am thinking about getting a round 24' seaspray evolution. Comes with a package and has Hayward 250 lb sand filter and 1.5 hp pump. $2363. Is price with me installing or I can pay a third party $850 to come do it. Is this a good pool with a good filter and pump setup?

My second question is that my back yard slopes a lot. I have a backhoe and can dig a level spot but was thing that water will still run off hill and wash out the pool. Could I do a gravel base with coragated pipe to catch water and divert it so it want wash the sand out? Don't know much about pools but not sure I am thinking right. I have another spot it could go. But this spot will allow me to tie in to existing 16x32 deck.
