I bought Zoo Med's Reptivite with D3 for my 3 month old veiled cham. I have been using it twice per month. My concern is that the supplement seems really grainy, not dusty like calcium dust. I used a mortar and pestle and ground it up finer but my crickets still don't look very dusty when I add the supplement. Is there something else I can try or a trick that you all know? I want to make sure he's getting all his vitamins. Thanks in advance.
