I know a guy that has a 4" pvc pipe about 5' long that is capped on one end and has a screw in plug on the other. The pipe has numerous holes drilled in it and it suspended in the water by a rope. He fills this pipe up with fish pellets in order to supplement his forage. He thinks it works well because it looks like an aquarium around his pier. Does anyone have any input on this type of supplemental feeder. I'm going to build one for my pond unless someone can give me some negative feed back. ???????
