Sera KH Test for the exact determination of the carbonate hardness in fresh or marine water. The test is sufficient for 390 °dKH. In a community aquarium the carbonate hardness should be between 5 and 10 °dkH (saltwater 8 to 12 °dkH) in order to guarantee sufficient pH value stabilization. The sera kH-test makes it easy to determine the carbonate hardness.

I'been using this product for many years now. Always accurate readings. Also very distinct colours ( from blue to yellow). It lasts for a long time even after opening the bottle.
