I agree with niloc16, a 32 gallon tank is too small for a sailfin tang, or any tang for that matter, ( sorry to sound like the tang police)
as for the fluval, I would not use the foam prefilter either and in the baskets I would use carbon and phosphate media.
You should be filterring your tap water as well with an RO/DI filter, to avoid algae problems.
As for equipment I would invest in a skimmer and you will need more flow ( circulation ) in the tank, with a powerhead or two
