I wonder about injecting soft corals with simple syrup. Just a tiny amount, using a syringe, and observing if it boosts coral growth, color, activity, etc.
+1 for brewer's yeast! The poor man's broadcast coral food.
Interesting. I have used a hypodermic to inject air or vinegar into invasive sponges and ball hydroids. Are you planning to inject the syrup into the corals flesh or just around the polyp? Have you considered diluted corn syrup? Would really like to hear your results.
Honestly, I haven't directly fed Brewer's yeast to my DT... At least not on purpose. I also activate dry yeast with warm water and anything sweet to feed my rotifers, copepods, and adult brine shrimp. I'm sure a little yeast remains in solution when I feed those to the main tank.

H2Oculture, when you say "broadcast", are you feeding corals the Brewers dry or in solution? When I use it dry outside, the slightest breeze takes half before it hits the water:wildone:
In that application I have to use it dry so it doesn't sink too quickly and foul my cultures before the animals consume it.
