The largest question on the pump is how much extra do you want to spend up front to save money in the long run? A small single speed pump would be fine, a two speed pump costs more and saves electricity, a variable speed pump costs even more and saves even more electricity. The financial payback depends on your electric rates. High rates make the variable speed pump a good deal, low rates make the single speed pump more attractive.

I like sand filters, very easy to use with minimal fuss. Every kind of filter has advantages, there is no clear winner for all pools.
