i dont feed mine meaty foods, the last time i fed meaty was last week, and the time before that was like 2 months ago. I find that if i dose Calcium, Magnesium, and Alkalinity and keep the levels good, and regularly dose phyto i can run my tank without much coral growth. But since i have been feeding this Ultra Min F food for the last month, my acans have sprouted 5 baby heads, and the two large heads on the frag have gone from quarter size to half dollar coin size. I highly recommend this stuff. Just 1 small pinch per day in my nano, and 2 pinches per day in my 55 work great. The label says for sponges, clams, and gorgonia, but my LFS guy said it would help all my corals, and it did. 25 bucks for about a years worth of food, not a bad deal.
