Question about Elos KH test kit.

[Douglas]

I've been using these test kits for that longest time, and have noticed a change in the newest kit i have purchased. It states in the instructions,

"Each drop of reagent corresponds to one degree of hardness. The total number of drops used equals the total hardness of the solution in 'dKH for example 4 drops = 4 dKh."

Now, the newest kit i've purchased states.

"Each drop of reagent corresponds to one degree of hardness. The total number of drops used equals the total hardness of the solutioni n 'dKH for example 8 drops = 4dKh."

Which is correct? I don't want to over dose to raise my KH.
