Pat hit a couple of my thoughts/questions. Feeders that are adjacent to or are in deeper water have always worked better for me. The deeper water gives the fish a place to retreat in both hot and cold water, but stay close to the feeder. TSC fish food, although made by Cargill, is not the same quality as their Triton hatchery line. Several quality fish foods are out there that can provide the same or better nutrition with less food fed. Expect to pay 80 cents to $1.10 a pound for quality fish food. I also always have some kind of cover close to my feeders for 2 reasons. One, it provides protection for smaller fish that stay near the feeder, and two, some ponds can be like roulette wheels. Fish can keep moving until they find a location that makes them want to stop. A brush pile is like that slot on the roulette wheel that the marble falls into.
