Ideally, you'd set the timer to feed whatever amount of feed would be eaten in 10 minutes or so.

Up North, we see fish stopping the eating of feed at around 50 degrees water temp.

Depending on your water temps, you may have the benefit of being able to feed year-round.


Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
