In a 22K gallon pool, a 1 HP pump should be more than enough--my pool is approx 29K gallons and I have 1 HP on it, and it does just fine. I'm also a proponent of sand filters--I think they do just about as well as a DE filter without all the hassle. Besides, you can always add a handful of DE to the sand if you need it to filter finer stuff.

Morehead is a good company, one of the pricier ones in this area, but they are also one of the only pool companies in this area that have such a full range of services without having to go to an independent contractor. They seem to be knowledgeable about what they do. The few dealings I've had with them, I've found them to be at least on time and deliver what they promised. I have found, though, that if you just need parts, i.e. gaskets, replacement plugs, Polaris parts, etc they are available for about 1/2 the price elsewhere. Just FYI-----

Let us know how it goes!!
