OK.

Then generally speaking, I'd recommend the following:
+ Hayward 3/4 HP 2 speed pump running 24/7 on LOW.
+ Hayward 30" sand filter (easy to clean; very long intervals between cleaning)
+ Polaris booster pump pool cleaner.
+ Intermatic time clock for Polaris
+ Hayward / Goldline SWCG
+ white / light plaster or DiamondBrite type finish

Hayward, because (a) they honor their warranty on direct to end-user sales (Pentair does not) and (b) on the items listed, Hayward has the best, or nearly as good as the best, product. The older model Polaris 280 is very reliable and functional, and parts are available widely, plus lots of pool guys know how to work on one. You'll need a cleaner on an unscreened pool in Miami. Plaster should be light, since pools in Miami tend to overheat; dark colors can add 5 - 8 degrees!

BUT . . . you need to commit yourself to 5 minutes per day, plus 30 minutes more each week. If you can't do that, bail out now!

The pool above, in conjunction with our methods, will allow you to walk-away for 7 days for vacation, business, etc, but you cannot do this routinely. One frequent poster here has likened pool care to goldfish care: it doesn't take long, but if you simply ignore things, you end up with a stinking mess!

Do NOT get a pool unless you are really committed to the 5 min/30min plan OR unless you intend to hire a pool service. There is NO pool design that can be routinely ignored for 2 weeks!
