I do have 1 feeder running twice a day for about 5 seconds. I will probably increase that now. I do have a lot of CNBG ... I have stocked 700+ over the last couple of years, and my banks are lined with BG beds. Shortly after the pond filled I put in around 10 PVC trees, a pallet pile, and a couple of tires in, and I have plant life surrounding about 60% of the banks. Air is next on the list!
