First saltwater tank equipment choices

[bluesman]

Ok, so revised setup is now:
30 gallon xl tank, with eggcrate top
20 gallon long sump with fuge
Reef octopus NW 110 skimmer
Mag drive 7 pump (nothing wrong with this?)
2 100watt heaters (any recommendations? I'd like one that is less than less than 11" so it can go width wise in the skimmer chamber)
3 powerheads (recommendations?)
For lighting: either the sundial 4 x 54w or nova pro 6 x 54w
$97 difference in price isn't that huge. I do like the features on the sundial. I don't really know jack about corals, does it really make that big a difference for what I could keep?
*edit*
and while we're at it...
Is the Coralife pure-flo II 50 gpd 4-stage RO-DI ok, or is there something else that I should get?

with the pro, you dont have to upgrade, EVER, you could even keep clams under that thing with as short as your tank is, on the pump, u should be golden, and on the powerheads, u should only need 2x hydor koralia 1's, possibly 2's, but im gonna say use the same setup i was gonna use for a 20g long tank i was gonna build and say that 1's will be plenty
the ro di unit i have no say so on whatsoever, i havent even begun to look at those things LOL im workin on information overload as it is
