When things get out of whack it takes a while to straighten out but it sounds like from what you've said the RW is rising. Keep removing LMB and adding large BG to the pond and you should see a difference. On the fish food I would cut the amounts until they eat it all in a few mins. And most of all use a higher protein (40-45%) feed for the BG.

PS do you have plant life close to shore for the YOY to hide in? If not chunk some of your cedars in close to the bank will help
