I have read many threads on don't feed more than the fish will eat in around ten minutes.

I have a hard time seeing the small pellets I feed. I have 0.4 acre pond with a lot of fish in it. I have a TH and am feeding 8 seconds at sunrise and 8 seconds at sunset. I have watched and they swarm when the feeder goes off for a couple minutes then stop. If I then manually activate the feeder for a few seconds they swarm again then stop. I have sat there and manually operated the feeder 5 times for 3 seconds each and every time they swarm for a little while then stop. I am guessing they are eating it all but don't know for certain.

It seems they will eat as much as I throw.

Is there another guideline on a maximum amount of feed per area per day or week that I should be concerned about?

Is two feedings a day at sunrise and sunset good or should I have more feedings with a shorter duration?
