need API KH color card

[AudraM]

I bought a used tank a bit ago and it came with an API KH test kit that was missing the color card. Anyone have an extra or can take a picture of theirs for me?

I don't have one unfortunately, but just remember the colors may not show up exactly the same after being processed by the camera and displaying on a computer screen. They should be close enough though. In cases, where people have really bad color display on their monitors, I know the nitrate card can come out funny.

there isnt one. each drop is one degree. when i think it changes to yellow thats your kh level. 10 drops = 10 degrees. ill get the right color and everything once i get home. i think 1 degree also = 17.9 ppm

Mgamer20o0 is right. The number of drops equals the degree of KH. The first drop changes it blue then when it changes to yellow thats your KH. The instructions say to cap the test tube and invert after each drop.

ah, see. I assumed instead of reading the directions and my hubby likes to say when you assume you make an a** out of you and me:nilly: Thanks, guys.

I have a question about the test too! I am so confused....:rolleyes:

When I do the test, the agent comes out of the bottle yellow and doesn't turn the water blue at all. Is that normal? (I don't think its expired yet.)

Also, how yellow should it get? Like a dark yellow or pale yellow?

check the date code, if its out of date, toss it, My first did the same thing, come to find out it was 6 years old.

bright yellow. at least mine does. if it goes yellow right away you have 0 kh.



In response to your question, each reagent bottle has a Lot # printed on
the bottle. The last four digits are the month and year of manufacture.
Example: Lot # 28A0102. This is a pH reagent manufactured in January of
2002. Pond Care Wide Range pH, Ammonia, High Range pH, Nitrate,
Phosphate, Copper, Calcium and GH all last for three years. Nitrite and
KH will last for four years. Freshwater pH(low range) and Pond Care Salt
Level will last for five years. I would not trust these kits after they
have expired.
