I am the caretaker of an 80 gallon freshwater community tank at my church. It's well established and looks pretty (lots of neon colors for the preschool hallway!!). Anyway, we have a cheapy petco automatic feeder since there is no one there to feed every day. I cannot find a place on the tank where the feeder doesn't get wet. I checked on it last night and the food had liquified in the little cylinder because of the backsplash of water from the filter. Anyone have another solution for a waterproof feeder? Or does anyone have experience with those 14 day pyramid feeders? I'm getting tired of cleaning out moldy (or worse) fish food and I'm sure my fish would appreciate a steady meal schedule!!
