For whatever reasons, I am on the opposite end from most folks...My feeder throws once a day, about 1/3 cup of Optimal Blue Gill and it takes my HBG from 15 to 30 minutes to clean it up. Occasionally, plenty of feed floats off and the minnows push it around until it sinks.
I guess the natural forage is so abundant that the pellets are just icing on the cake. My original stockers are bulging at the seams. I have recently put the feeder back in the shop and will only hand feed to lessen the amount of waste going into the pond. This means an occasional missed pellet meal on rainy days or when I can't get to the pond for whatever reason.
My original goal was to supplement feed, but now I worry about having left over pellets at the end of the season.
I don't see why you couldn't feed them as much as they would eat, up to your feed budget. Something tells me you should look into creating more natural forage.
