Aquavascular KH Test Kit

Aquavascular KH Test Kit – Carbonate Hardness (Alkalinity) Tester for Freshwater Aquariums

The Aquavascular KH Test Kit is a reliable titration-style hardness test that measures the carbonate buffering capacity of aquarium water. KH directly influences pH stability, preventing sudden drops that can stress or harm aquatic life. Maintaining proper KH levels is especially important for planted aquariums, aquascapes, shrimp tanks and systems using RO/DI water.

This kit provides clear and accurate colour-change results, allowing aquarists to determine KH in degrees (°dH) and make informed adjustments to water chemistry when needed.

Specifications for Aquavascular KH Test Kit

• Product Type: KH (Carbonate Hardness) titration test kit
• Suitable For: All freshwater aquariums
• Testing Method: Drop-by-drop reagent titration
• Colour Change: Blue → Yellow
• Accuracy: 1 drop = 1°dKH

How to Use the Aquavascular KH Test Kit

1. Take 5 ml of aquarium water in the provided test vial.
2. Add KH reagent drop by drop.
3. Shake the vial after each drop.
4. Stop adding drops when the sample changes from blue to yellow.
5. The number of drops used = KH value in degrees (°dKH).

Care & Maintenance Tips

• Test KH weekly, especially in planted or CO₂-injected tanks.
• Use KH boosters or buffers if levels drop too low.
• Maintain stable KH to prevent pH fluctuations.
• Store reagent in a cool, dark place for longest accuracy.
• Rinse test vials after each use to avoid contamination.
