I have to disagree with most that have posted. I started my first SW tank in November. Used live rock, but dry aragonite. I rushed the cycle process using pure ammonia. Once it cycled, every day Id add a little more ammonia to try to bolster the biological counts. All in all, it took about 3 weeks before I started adding livestock or corals. About two months in, I added an elegance coral, and a couple weeks later added an amazing SPS frag pack from a loval private sellar. Hes now a very good friend, haha. It was loaded with stellar sticks: WD, Wolverine, PC rainbow, Tyree pink, The Vihn, Northern Sasquatch, Tierra Del Fuego, Pink Cadillac, Sunset Milli, etc. My tank had been extremely stable, so I felt comfortable and it worked out. Now, after 4 months, everything is not only still alive, but also thriving. For the record, I don't use reactors, a controller, a dosing system, or any other fancy gear. I have cheap blackbox lights and pretty much cheap everything else. I do target feed, test, and do water changes on the regular though.
I'll also add that I do not recommend this approach for everyone. I wasn't experienced, but my good friend has a marine bio degree and owns his own SW-only LFS. So I was given incredible insight.
