Pat, I couldn't agree more.
But my money is on those nasty little bloodworms as the culprit based on the symptoms and having had a bad experience this year myself.

I don't know how much you invested in the bloodworms, but I'd toss what ever you have left in the trash.
Like I stated earlier I was able to get a refund from my source, so maybe you can try that as well.
As far as what is actually wrong with the bloodworms and what ailment they might be causing or how to treat it, I'm at a loss. All I did was discontinue use and my discus recovered within a week with no treatment. The Cardinals not as lucky
Good luck
