I wouldn't get coral right away. See what the tank reacts like with some fish in there. Their poop will throw parameters off ideal levels for coral so making sure you can control it quite well with whatever filtration you are going to implement or add-on is a good way to take control. Start with a couple small fish to start the bio process. example-two clowns, then add a gramma later, then add a wrasse, and so on. Make sure you can control your parameters through filtration and that what you have is sufficient enough. Corals will never do well if you don't start there. You can to the right place. Good luck.
