I'm looking at all the options and reviews but not sure what would be best since I've never owned a pool before. They are gonna dig this week, so I thought I better get this ordered. Our pool will be a 20x44x30 with a 6x20 sun deck and underliner steps. Looking at the Dolphin oasis Z5 but really don't want to spend that much if possible. We are lucky because we don't have any close trees, so leaves will only be an issue in the fall when they blow from the neighbors. Suggestions please.
