Product: Blu Bios Test KH
The carbonate hardness (KH) is used to maintain a stable pH value.
Buffers changes, caused for example by the decomposition processes in the aquarium and ornamental pond or consumption of carbon dioxide by plants.
A carbonate hardness is too low due to the changes of pH value.
KH values between 5 ° and 10 ° create optimum and stable in community and provide the basis for a luxuriant growth of plants.
The cichlids from Lakes Malawi and Tanganyika require higher values.
In the marine KH value must be over 12 ° DHK.
Instructions for use:
Shake well before using the reagent!
1. Rinse the tube several times with the water to be tested and then fill it up to the 5 ml mark. Dried, then, the tube externally.
2. The reagent is added drop by drop. And 'necessary to shake the tube after each drop added until the color changes from' all blue 'orange
3. The number of drops used corresponds to the carbonate hardness (° dGH), pe 5 drops = 5 ° dGH
4. Cleaning Before and after each test is necessary to clean the tube thoroughly with tap water.
