Tums,
You're absolutely right on everything you said. I wasn't aware you had experience with high density catfish. And yeah if you wait for diagnosis it's usually too late. Been there done that! The diagnosis lab refused to even give me an idea. Last time I wasted my time on that. Took weeks to get an answer back!
Now I just manage my ponds to lower density and stress and I usually don't have any issues. I also don't bring in fish from wild sources.
Yes you only need a few ppm of chloride from the NACL to aleviate brown blood disease from nitrites. I thought you were trying to achieve 0.5 percent or something.
