The Bee Smart In-Hive feeder holds 1 gallon of syrup or water. Place it on top of frames and put an empty super over it. Landing pads and steps prevent bees from drowning. Tank is translucent, so it is very easy to see level of syrup left in tank. This feeder is drip free so feeding is not messy. Just remove tank, refill and place back on base to continue feeding.
