It's interesting how things has changed from the years of everyone trying to achieve 0 ppm of nitrates and phosphates to the convention that you want some of both in the tank nowadays. As for aminos, there's actually quite a number of successful sps dominated tanks that run them, even when their target nitrates are hitting 2.5-5 ppm nitrates, which I wouldn't call ULNS by today's standards. However, in those tanks, I'm pretty sure that amino has less effects than in ULNS systems. With 9 fish in the tank, and a couple of them being anthias, food is always in abundance. I'm actually interested in trying out a non-photosynthetic gorgonian (not a blueberry) or another softie in the tank to see how it would do.
