I have that kit.

For PH, you add pool water in the big vial to the top indicator line. Then add 1 drop of solution #4 (chlorine neutralizer), swirl, then add 5 drops of #2, the phenol red. Swirl and compare to get reading.

For Alk, you add pool water in the big vial to the bottom indicator line. Then add 1 drop of solution #4 (chlorine neutralizer), swirl, then add 1 drop of solution #5 (the blue alk one) and swirl. Then start adding and counting drops of solution #3, swirling between each drop, until the water clears. Multiply the # of drops x 10 to get the alk reading.

Those are the ones I run. I can get you the acid demand test if you'd like.
