Hmmm, I don't have that many large fish. 25 HSB, and 60 (now 59) SMB.
I'd like to know where those HSB hang out. Maybe this will help. I just have one acre, and it could be a bit smaller than that. Basically a square pond. Not tons of cover, but enough. I still have lots of FHM, and lots and lots of GSH.
I may give this thing a try. My birthday is next month.


12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
