hay man a clean and properly set up fowlr is a great start for a reef tank. Keep it a fowlr for now, when buying equipment keep i mind the future reef. Then after you have all the proper equipment make the switch.
this is a list of what i think are necessities for a reef tank...
standard tank with built in overflow(s) 24-36-48 inches (easier to buy lights,hoods and stands for these tanks)
Sump W/ return pump (any small plain tank will work)
pc lighting or better(I bought 3 hagen t5ho fixtures for my tank one at a time. Witch makes it easier on the wallet)
salt, hydrometer, thermometer
protein skimmer
chiller (not truly a Necessity but the stability it gives works wonders for the tank.
