tim k,

I read the Pond Boss forum for expert advice on a multitude of topics. I also believe that you have received solid expert advice on this thread.

However, there are too many variables in "pond science" for remote expert advice to work all of the time.

I highly recommend you perform the experiment on your own pond! Run your feeder a few days and observe the response.

Take a temperature reading at a fixed location while performing your experiment. If the BG don't feed now, they may start feeding in +2 degrees from now. If that is the case, then you will know approximately what temperature your pond needs to achieve in 2023 to start your feeding program coming out of NEXT winter.
