Api Kh Test

[peter_uk]

I have the API KH test which i was about to use except i seem to have lost the instruction on how to properly use it.
I have checked the API website and searched online, could someone please advise on how to use the test.

thanks

might be wrong but I believe that for GH and KH, you don't need the colour cards, which is why you wouldn't have them. You are supposed to count the drops it takes to turn the solution from green to red (or whatever, I can't recall the exact colours) and then that is your hardness level.
My testing kit is API. To test GH or KH, I fill the vial to 5mL, and put one drop at a time of whichever solution. If it takes 3 drops to turn it from green to red, then the hardness is 3.

I just sent you a PM with a link to a scan I made of the instruction sheet.
