Don't know, I do know lots of people are using it and getting good results, from what I have read.
When you do the blender mush, how do you feed it?
I put the blended mush in ziplock bags and freeze it, after a day or so, Icut it up into little meal sized chunks, take a chunk, thaw it in a cup of tank water, break it up and pour it in the tank. There are fish sized chunks all the way down to liquified. It feeds everything in the tank from the worms, pods
and critters to the corals and fish. It is possible to foul the tank with any food, I have found the proper amount of mush to feed everything and not foul the tank.
