Well that’s a great solution. I have no power at my pond, but you’ve got me thinking. I wonder if I could tie in a deep cycle RV battery. Just sit it by the feeder. I still haven’t swapped out batteries to see if that will fix my upper motor. Had knee surgery this morning, so I’ve got lots of planning time on my hands. (90 miles from the pond)

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.
