I've always been advised to feed my perch right before sunrise and right after sunset. They aren't as afraid of the sun as I thought they'd be, maybe they are starving. I'm feeding 10 seconds in the morning (after sunrise) and 10 seconds in the evening right before sunset. The food gets cleaned up in seconds. It's a continuous adjustment as the feed I get (Optima) seems a different size with every bag. It's difficult to change the settings on the feeder, but it's easy to change the timer. So I just adjust the amount of time the feeder runs. Hoping I am throwing out about the same amount of food.
My perch are not as large as some I see on this forum. I'm limited by my budget.
Maybe one of our more knowledgeable guys will jump in here with some advice. Although I put Dono in that group. Maybe I should be rethinking how I feed.

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
