JBL ProAquaTest Carbonate Hardness KH REFILL contents: 1 reagent

Why test for KH?
The well-being of aquarium and pond dwellers and the growth of aquatic plants depend to a large extent on the KH level being kept as constant as possible. The carbonate hardness is one of the most important water values since it keeps the pH level stable. The KH should never drop below 4 °dKH.

Recommended KH Values:

• Freshwater aquarium (community aquarium): 5-12 °dKH
• Lake Malawi/Lake Tanganyika aquarium: 7-20 °dKH
• Plant aquarium with few fish (aquascaping): 3-8 °dKH
• Marine aquarium: 7-10 °dKH
• Pond: 7-10 °dKH

You can analyse the water values you have measured in the JBL Online Laboratory free of charge and receive recommendations.
