API Carbonate Hardness KH Test – Fresh/Salt ^59

Carbonate Hardness (KH) Test Kit for Freshwater & Saltwater Aquariums

Maintain stable and healthy water conditions with this reliable Carbonate Hardness (KH) Test Kit. Designed to test tap water as well as freshwater and saltwater aquariums, it accurately measures carbonate and bicarbonate ion concentrations—also known as alkalinity.

Monitoring KH is essential for preventing sudden pH swings that can cause stress to fish and other aquatic life. Regular testing helps ensure proper buffering capacity, keeping your aquarium environment stable and balanced.

Key Features

• Suitable for tap water, freshwater, and saltwater aquariums

• Measures carbonate hardness (KH) and alkalinity levels

• Detects potential fish stress caused by rapid pH shifts

• Helps maintain proper buffering capacity

• Easy-to-use 1 bottle liquid test kit

• Provides accurate and reliable results

Why Test KH?

Low KH levels can lead to unstable pH, which may cause stress or harm to fish. By routinely monitoring carbonate hardness, you can maintain consistent water chemistry and create a safer, healthier aquatic environment.
