There is moisture collecting on the inner cover. It may not be an issue since the condensate just drips into the syrup tanks. It also may be degrading the Masonite board. I am using a top feeder with the inner cover and telescoping cover above. Should I be using the inner cover? Wouldn't the moisture just collect on the telescoping cover anyways? I am wondering if should ventilate the area between the actual syrup reservoirs and the top of the frames? I was thinking about drilling three to five 3/8" holes in in a line into the front of the feeder box itself. Is it wise to create a top entrance in this fashion?
