So I found your tank thread. Honestly I would wait before trying acros.
I have some other corals in my tank that I recommend. I have a Jason Fox Green Psammocora, an ORA purple stylo, an ORA montipora confusa, and a Red Montipora cap. Your tank is still very young and these corals are hardier. These corals are considered starter SPS. If you see growth in a few months from one of these then you will have a better chance of success with acropora once your tank begins to mature.
