Spirulina as a food source?

So has anyone tried supplementing/feeding spirulina powder in their reef tanks? It seems to be a very nutritious food:

Almost 60% protein ain't bad. It has a good amount of fats too:

 

 

The fatty acid profiles of six commercial tablets pro- duced from S. platensis in Turkey and one from China were determined. The samples contained 33.68-66.75% saturated fatty acids (SFA) and 28.20-47.78% polyunsaturated fatty acids (n-3 and n-6 PUFA). Spirulina platensis is a rich source of gamma linolenic acid (GLA), which accounted for 4.07-22.51% of the fatty acids. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were found in only two samples where they accounted for 1.79 and 7.70%, and 2.28 and 2.88%, respectively. There was a significant (p<0.05) variation among samples in total SFA, monosat- urated fatty acids (MUFA), PUFA, GLA, total unsaturated fatty acids (UFA), and ratio of n-3 to n-6 PUFA.

And it's like, ridiculously cheap compared to most things we dump in our tanks. Anyone?

Spirulina flakes exist and are pretty common. I have the Ocean Nutrition brand and the fish like it. They don't go crazy about it but they do eat it. I mixed some of it in with my homemade frozen food.

Yes, the food is quite nutritious. I've been feeding Hikari Spirulina Brine Shrimp and many DIY food recipes include spirulina.

 

Oh, yeah, I use that stuff for my suns. Second to none for feeding tubastrea.

I know about those, but I'm asking about pure, uncut, spirulina:

What would want to eat that?

 

I'd imagine in the reef it would be good for filter feeders that feed primarily on plankton like gorgonians, fan worms, clams, and goniopora. I imagine it might be good for other corals that eat really small things like SPS and zoas?
