Mike I have been trying out the Micro and Macro feeds as well.
It is too soon for me to give an honest critique of it.
What I have noticed so far:
Both foods upon immeditely opening the containter you notice the smell garlic and krill.
Non-photosynthetic LPS corals do not have the same reaction to this food as the Fauna Marin food. When the Fauna Marin food is fed the corals' polyps are extremely expanded/swollen. This could also be because the macro is a hard pellet and the Fauna Marin is a soft pellet making the coral digest the Fauna pellet quicker/easier.
For the micro-feeder, gorgonians accepted it when they were spot fed. Mixed 1/2 a cup of aquarium water to 1/8 of a teaspoon of micro-feeder. This food did look close to the consistency of MinF and a little redder in color. This food most likely be used for additional supplementation to what we are currently using.
For my honest opinion: I can see the foods selling in high volume due to the price and availability. Spectrum does make quality foods, it trusted brand, and are pretty much available at every LFS. This is Spectrum's advantage. What I find is more interesting is that Spectrum made this type of food and I wonder if more aquarium food makers will follow suit.
