It is but very expensive!

Good, I suggest that you start with a FO tank, save money for the
lighting system and then go to reef.
I didn't see any references to lighting, if you did, what kind of
lighting are you going to use?
Then, is there the issue of inverts and their poor tolerance to chlorine.
Reef keeping isn't easy and a good RO filter can save you a lot on the
long run when filtering destilled water.
Do yourself a favor, start with fish only (FO) then take a step to FWLR.
Once you've mastered the sal****er issues it will be easy to step into
corals. They are expensive and hard to maintain.

Maintaining corals-only tank with no fish is actually easier than FO.
