Testing KH

[toniell]

I just got a hagen KH test and I don't understand it on most other hagen test's the back of a booklet tells you your result's on this one it just shows the coulor it should start out as blue and the colour it should end up yellow I can handle all that but now it's tlling me to multiply the numbwer of drop's I put in by 10, it took 15 drops, now it is showing these conversion table's and it's pretty confusing if somone could explain this a little further for me it would be greatly appreciated.

KH is the carbonate hardness of yoru water.you are dealing with the stability of yoru water, being able to maintaine Ph.
when you add the first drop it shoudl have turned a blue color. the last drop you counted shoudl have turned it to the yellowish/pinkish color.
when you multiply by 10 you will have 150. this should be what your KH is in mg/l.
