Jbl Proaquatest Kh Refill - Carbonate Hardness Test Refill

Condition: New

JBL PROAQUATEST KH REFILL is a reagent refill designed for accurate measurement of carbonate hardness (KH) in freshwater aquariums, marine aquariums and garden ponds.

Carbonate hardness plays an important role in maintaining stable pH levels and a healthy aquatic environment. Regular KH testing helps monitor the water’s buffering capacity and prevent sudden pH fluctuations that may negatively affect fish and other aquatic life.

Key Features:
* Accurate measurement of carbonate hardness (KH).
* Suitable for freshwater aquariums, marine aquariums and garden ponds.
* Easy-to-use drop test with a clear colour change.
* Helps monitor pH stability and water quality.
* Quick and reliable results.
* Genuine JBL reagent for refilling an existing test kit.

How to Use:
Fill the test vial with 5 ml of aquarium water. Add the reagent drop by drop, gently mixing after each drop, until the colour changes from blue to yellow.
Each drop corresponds to 1°dKH (German degree of carbonate hardness).

Package Contents:
* 1 bottle of KH test reagent.

The number of tests depends on the carbonate hardness of the water. Higher KH levels require more reagent drops per measurement.

Storage:
Store in a dry place at room temperature, in the original packaging.

Important: This product is a refill reagent only. It does not include a measuring vial. The measuring vial from the original JBL PROAQUATEST KH test kit is required to perform the test.
