This reagent is the third and final reagent for the total alkalinity test. R-0007 is added to pool water along with R-0008 to produce a color change to green. Then, R-0009 is added to produce a color change to red. The number of required drops is multiplied by 10 to determine the total alkalinity result. This one ounce bottle is sufficient for over 70 tests.
