So I'm thinking about buying all the parts and then having an installer install it..

The pool that my local store has that we like is called "Quest" and I found it sold online here: http://www.thepoolfactory.com/quest-24x54-round.html#

So other than the pool, I need advice on the pump / filter.. I read recently that for up to 24' you should get a 1HP pump and that getting more than that is actually counter productive.. Is that true?

Also, sand or cartridge? I'm leaning towards cartridge..

Thanks
