Clam Shells for Soil Ammendment
I have a bucket full of clam shells (fully cleaned) and I was planning on grinding them up and sprinkling them in my veg. garden for the CaCO3 content....seems like a benign way to recycle this would-be trash....any reasons not to? The soil, tested by one of those color-coded pH measurements, is not overly alakaline to begin with.

That's a great idea, especially if you are careful about the pH.
Keep in mind, since you are grinding them up, they will have a very strong effect on the pH. If your plants start looking nutrient deficient, even when you fertilize, then use sulfur to bring the pH back down to where the nutrients will dissolve.
A sulfur-coated slow-release fertilizer will work nicely
