Great pic, Guy!

Has there been a discussion about the best substrate to facilitate the fish plucking up the pellets that have settled to the bottom of the pond?

I was thinking of an old tractor tire placed horizontally and filled with packed sand. That would get the food landing zone a little off the bottom of the pond, and hopefully reduce the amount of silt mixed in with the pellets.

The fish would get a little sand in their mouths, but they should be able to spit that out?

Surely there are better options than a soft, silty bottom where the pellets sink in and decompose. Or a gravel bottom where the pellets can get into the interstitial spaces where the fish cannot pick them out.
