I think I'm on the other end of the scale. I believe I may stop feeding it. Last week I fished the pond for a few hours. I have primarily a YP and SMB pond. I added a few HBG a year and a half ago, so that the grandkids would have something to catch in the middle of the summer days. Last week I was only catching HBG after the sun had been up for a while. The HBG are doing very well, for not having been in the pond all that long.
My problem is, the SMB and the YP haven't grown much at all. I'm trying to keep as many HBG as I can, but they might be out reproducing the YP and for sure the SMB. Maybe I'll go back to Purina. I just don't remember which AM size to go with.

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.
