JUst found a bag of organic spirulina powder that the ex left behind, since it is powdered seaweed I was wondering if I can feed it into the tank, for the tangs and corals etc?

being powdered i doubt it would benefit the tangs, not sure about the corals.

Add some water, make it into a very thick paste, Make into seperate pellets or bit sized praportions, leave to dry, or put under low heat in oven for a few minutes, Got yourself Biscuits/pellets.

Spirulina isn't seaweed. It's a freshwater blue green algae.

But, give it a try, could be good for any filter feeders.

Interesting, I always throught it was seaweed. I tried a little bit in the tank, the fish ate it but them I had a look in the skimmer and found most of it in there. Don't think I will bother again.

Spirulina is a blue green algae and Bob Fenner recommends it as a component in reef tank mash.
