What makes our Krill Flake the best flake on the market, ingredients and production. We start with the best marine proteins, add farm-raised spriulina algae and all the required vitamins and minerals as well as some extra natural ingredients to promote health and encourage breeding. Then we flake it so it crisp and thin and you get our Krill flakes. We've had it for many many years as Marine Crave Flakes, now after lots of input from our customers we are promoting it for freshwater aquariums as well. So far, we have found no other flake like it on the market.
