Joe, I wasn't even thinking that technical. Like Ewest says, 10 lbs/acre/day is the upper recommended limit. That's pumping a lot of nutrients into the pond via the fish. If all you readings look good, the fish look good, and the secchi depth stays 18" or greater (ooh - and you don't get a huge growth of chara or submerged plants or ???) - I'd say you're keeping an eye on everything and it looks ok.

Bruce Condello once posted one of his earliest pondmeistering efforts. He had a very dense stocking of HSB and fed them like crazy. His story went something like "I had a world-class HSB fishery for three years, then there was a fishkill and they all died." This is the kind of situation you want to avoid.
