Hi, I am missing the color indicator card that came along with the GH kit.

Can somebody help me find the link or scan their card for me so I can read my test.
I have never thought of using it until I was setting up planted tanks, and now when I need it I can't find it.

Hey Jocky, there is no card for GH & KH in the kit. Just count the number of drops it takes to turn the color from red to green. The number of drops added until the color change will represent the lvl of hardness. The same is for testing KH. The number of drops to change the color from Blue to Yellow, will represent the lvl of KH.
If you get immediate color change in either case then your sample of water is likely less then one degree.

Yep no cards, Diesal got you covered.
