I like that one too! And if you're in a hurry you can use the half method which requires half the reagent and half the drops for a quick check.I find the Salifert Alkalinity test kit is very inexpensive and accurate. Just for $17, you get 100 to 200 tests. The color change is from blue to pink, it is easy to read. You can add one more drop of color reagent to make the color more intense.
