It's like Vitalin, a good alternative also good when used in conjunction with Vitalin, it contains chitin as well asbeing 20 % protein and it breaks down into very very tiny particles. There are two types granular, and the crumbles (the pellets). If your making a method mix, the pellets are horrible, they don't soak up moisture very well, granular work well for method and in groundbait for Bream, hope this helps Paul.
