George,Not sure about all the weights and pounds of fish.to be honest with you i thought we were just throwing enough food to keep fish around feeder,not really doing much for weight gain.now that i look at your feeded times maybe i'm doing more than i thought.i can tell you the 13 seconds total feed time does not take them much time to wipe feed out.my guess is within 6-7 minutes i have not feed left on the water.within the next day are so i will put a bag over the feeder and catch all the food it puts out in a 4 second time.then we can weigh amount of feed.i will post amount after i do this.in the mean time maybe someone allready knows this info. and can post for us.
