Anyone know where I may be able to pick some up? I searched TSC and no luck. Anyone know of a feed store open today?
 
out on 104 by MO there is a country max. it's on the opposite side of the road a little before you get to MO.
 
I wouldn't use it in the reef. I've tried it and I know others have but the stuff isn't clean. There is lots of particles and nutrients.
 
I'm not totally sure, but I think mollusk shells are at least partially Calcium Phosphate, which means if they dissolve they could give of phosphate.
