Dino X primarily targets most forms of Dinoflagellates, but can also be used against other types of algae as well.
Yes, some inverts such as Clams can be harmed during the treatment period. This is not because of the ingredients inside Dino X, but rather the toxins and waste that is released as algae and dino begins to die-off. For that reason, we always recommend users remove as much of the algae or dino as possible before starting the treatment. There are certain kinds of Dino strains which release toxins when they die-off, it is this toxin which poses a threat to inverts.
