Your gonna go through a $h*tload of food.. Feeding that much that many times a day.. Seems excessive to me.. I feed my fish twice daily for 1 second and I use 100lbs of food in under a month.. If I wanted too I could feed 100 lbs a week but you need to relize all the extra nutrient dumped in your pond.. My fish have grown amazingly in just a couple months I caught a 6-7" bluegill weighing 338grams right under 3/4 of a pound so it must be working..
