Taylor alkalinity test

[Threekids03]

Well after draining my pool, my CYA levels came down considerably to 70, though not ideal. When I performed the Taylor alkalinity test, at 7 drops the water turned from green to clear. At 8 drops the water turned pink. At 9 drops it became a deeper pink. Would the 8 drops be the completed test then? Or is there a certain shade of red I should be looking for?

Counting the number of drops as you go, add R-0009 one drop at a time, swirling to mix after each drop.

1. Continue adding drops until the color changes to something more or less red, pink, yellow, or clear. The sample may switch between green, blue, and gray while you are adding drops. That is not the color change you are waiting for.
2. Continue adding drops as long as the color continues changing. The final drop, that does not change the color any further, does not count.

So since 9 drops was darker than 8 I guess I'll go with that? I didn't add one more drop though to make sure it didn't change because the box just said "continue adding drops until the color changes from green to red". They didn't specify a shade of red.
