Haha funny you should mention that... it was actually developed to specifically feed GONioporoa lol. As I understand it, the food is a dried mixture of a specific zooplankton eaten by coral. The sample I received was a baggy of beige powder and when added to different tanks, I noticed feeding responses from nearly every coral. LPS is particular immediately put out some of the longest sweepers I have ever seen them put out. The weirdest feeding response was from zooanthids. The mouth of every zoo protruded out (like a nipple or something) and the zoo spread out as much as it possibly could. The micron size is 150-200 so it is fairly large for SPS but I did notice sweepers out after feeding. It could simply trigger a feeding response in SPS coral but IMO that alone is worth feeding it.
