I just received 6 more bags, and I can't tell if any significant amount sinks. I hand feed some right off the dock several pellets at a time, and never recall any sinking.

You might take a large clear plastic tub with water and drop 3 or 4 hand fulls in to test if any or how much sink. Then just dump it in the pond when done. No waste.
