TJ, I've got some of Scott's BG feed in the feeder. I bought a few bags to test.
Looks like the YP are taking it. I haven't really seen any results. 1/2 bag with a really low rate (2 seconds a day)
I guess this is just a FYI, as it really isn't any help to you. Sorry about that.

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.
