I may need to test run mine and try to catch what it spits out to see what each 4 seconds is really throwing out.
I may know it down to 3 seconds or even 3 feedings then. As I can not afford to feed 3 pounds a day plus seems like a ton of food.
I can tell you though that they eat all that is throws in the morning for sure as that is when I was there.
Plus when I threw more food out they ate it as well, I did this about 3 times by hand and seemed to get eating.
So I either have some hungry fish or too many. (Bank on the second)
Either way say they are eating all the food, and could even eat more would this be too much since the pond is so small?
