Looking at these five models and confused as to why Dolphin has so many variants, pluses and minuses etc. Don't really need a caddy as I have a storage box close by. Pool is freeform, 13000 gallon with a a sunledge and a bench under a waterfall. clover shaped with two lobes at 4' and entry lobe at 3.5 center is 5ft deep Our water is hard and lots of scale already on tiles and stones that form the waterline, so not sure if waterline will be a benefit worth paying extra for. Guessing rocks will throw it off some?
