If you're using strips...you might as well be guessing what your levels are IMO. It's definitely worth the $25-30 to pick up an API Master Test Kit. They're accurate and they last a long time. I consider them one of the absolutely vital tools for a healthy aquarium.

What's the highest you think I should eventually aim for in the tank to kill the ich? The barbs are supposed to be in a maximum of 82 degrees.
