Thanks for the welcome! The test kit that I bought was the Poolmaster 22260 Basic 5-way Test Kit. As Carl suggested, I put 1/4 cup of 8.25% bleach in the water last night before I went to bed. When the test kit arrived mid-morning, I checked the chlorine, pH, and total alkalinity. Chlorine was really really light, almost no yellow at all (lower than the 0.6 color), pH was lighter yellow than the 6.8, pretty acidic, and alkalinity was only ten. Reading a little about the BBB method, it said to add baking soda to bring alkalinity up and pH up. That pool calculator website was so neat, I added the amount that it said to add, and it was spot-on! Alkalinity was brought to exactly 50! Then I put in some borax to raise the pH and another 1/4 cup of bleach, and when I tested it later, the numbers were right where I wanted them to be. This is a neat website, so much useful information.

Thanks for your help!
