Sprkplug I have been feeding 2-3 pounds of feed a night. This will vary from night to night depending on weather conditions and how much they are eating. I also have been trying to stay on top of the vegetation. I have been raking the FA from time to time. Most of the bank is covered in erosion stone into about 2-3 feet of water so far no problems but will definetly keep a close eye on things.
