Al, don't feel bad, I use Prime on my QT tank, about 1/2 - 1/3 of what's recommended, along with a 20-30% weekly water change. Prime is not only used for ammonia removal/absorbing, it's also used for a stress coat, and that's more what I'm using it for in a QT. I use it at very small amounts when moving fish from one tank to another during acclimations as well. A lot of people are afraid of Prime because it lowers O2 levels, but that's only when you don't use it properly.
