I can't say definitively that is was the acid condition of the water that caused my fish loss, but other pond owners in that area had told me that their ponds had slowly lost fish due to the acidic conditions. I also had a large garden pond at Holly Lake Ranch which was in the area of my ponds, with Koy and Goldfish that seemed to do ok. The water was filtered and aerated, but when I tossed a few small CC in, they started coming belly up within a week or so. By the way, you can trap greenies and BG very effectively with floating funnel traps baited with a handful of floating catfish pellets. I make my own traps with pvc and plastic mesh and set out 2 or 3 traps at a time
I've trapped many BG and greenies, but never a CC or bass.
