I also used rock from Fiji almost 20 years ago when I built my existing reef. It was half what it is now and had a lot of die off, which made the cycling that much more extended. Doing it over again now, I would start with sterile rock and seed it. I think the time to a stable tank is maybe a little longer this way, but a lot cheaper and without getting the free loaders that live rock carries. Most of my free loaders were not the friendly kind.
