I get my feed from a local mill, 35% protein. Maybe 10% sinks and at first, it bothered me. Now, after feeding it for a few weeks I noticed during one particularly calm evening that even the sinkers don't go too deep before something grabs 'em. I don't think anything goes to waste if you don't overfeed...
