I had pretty much decided to stop all treatments on Sunday when I sent my first post. I realize frogs periodically go without eating-her tank mate that recently died went on "food strikes" fairly often and I never worried about it. Simon had never refused food and it was almost a month of very little food before I started medicating.
I use Koizyme as a water conditioner-to keep the population of "good" bacteria up, not as a medication. I have well water so I don't need any water conditioners. I do run the water through a carbon filter before adding it to the tank, though.
I'll try to post some pictures this afternoon if I can figure out how to do it.
