I was in on this product developmetn for the past year or so, and also ama distributor. I have a thread going in my forum, and information on my website should you want to see the nutritional breakdown.
It is a very versatile food- you can adhere it to rocks/wood for your grazers, feed it in cubes, freeze it and use a shredder (lemon zester works great) to place it in the water column, etc. It is fantastic for fry as it allows them to graze and the food stays stable in the water column for at least 24 hours, though I have left it much longer without fungus or clouding.
Another nice thing about it is that because of the stink, it is extremely palatable. This makes it a good choice for making medicated foods which can be added to the mix. Meds ingested are generally much more effective than those placed in teh water column.
Here is a link to my website which has the different formulas and nutritional information:

Please feel free to ask me any questions that you may have!
Right now there are four diets available:
Soilent green (an aufwuchs replacement)
Community plus- krill based community diet
Meat pie- for the carnivorous fish (catfish)
Shrimp Souffle- scavenger diet that is squid and krill based with added carotenoids.
There are several more diets coming out. Allen has said there will be a breeding conditioning formula (not a long term staple diet, but a supplement to condition things like apistos to spawn) that will have a very high fat and protein content. A color enhancer (Redrum) that is very high in carotenoids, a xlivore diet for wood eating panaques and another one which is skipping my brain at the moment.
