The carbonate hardness or alkalinity corresponds to the buffer capacity of the aquarium water and therefore determines the stability of the pH-value in the water. With these tests the carbonate hardness and alkalinity can be measured with precision in °dKH. The test liquids show a pronounced and obvious color change and are sufficient for approx. 100 tests.
Tropic Marin Water Test Kits are the result of intensive research and development - directed at the needs of the serious aquarist. Extensive testing has been completed to assure accuracy and reliability.
Tropic Marin tests are quick and easy to use. The kits contain glass vials, dosage syringes and recommendations to optimize the water quality.
