API GH/KH Hardness Test Kit (General Hardness & Carbonate Hardness)

This easy-to-use kit allows you to measure two crucial water parameters: General Hardness (GH) and Carbonate Hardness (KH).
Maintaining the proper balance of these minerals is essential for thriving fish and healthy plant growth.

Why is GH & KH Important?

• Stable Environment: GH & KH impact your aquarium's buffering capacity, which helps maintain a stable pH level.
  Stable pH is crucial for the health and well-being of your fish.
• Happy & Healthy Fish: The right GH & KH levels can help reduce fish stress, promote vibrant colouration, and even aid in successful breeding.
• Healthy Plants: Many aquatic plants require specific GH & KH levels for optimal growth and nutrient uptake.

Benefits of the API GH/KH Test Kit:

• Fast and Easy to Use: Get accurate results in minutes with simple-to-follow instructions.
• Reliable Results: Trusted by hobbyists for decades, providing you with peace of mind.
• Liquid Test Kit: Easy to use and store compared to strip tests.
• Compact and Convenient: Stores easily without taking up valuable space.

With the API GH/KH Test Kit, you can:

• Monitor your aquarium's water quality regularly.
• Diagnose and address potential water parameter imbalances.
• Take action to adjust GH & KH levels if necessary.
• Create a healthy and thriving aquatic environment for your fish and plants.

The API GH & KH Test Kit helps you duplicate the natural habitat of your fish to prevent stress, keeping them healthy!

Suitable for freshwater aquariums. 

Test kit includes:

1x GH test solution
1x KH test solution
2x glass test tubes|
1x easy-to-ready instructions

DIRECTIONS FOR USE: KH
Fill the test tube to the indicated line with aquarium water.
Holding the test solution bottle vertically, add the KH solution one drop at a time.
Be sure to count the number of drops being added.
Cap the test tube and invert several times after each drop.
The test is completed when the water in the test tube, after having been shaken, turns from blue to yellow.
The KH is determined by the number of drops of test solution that must be added to turn the water in the test tube bright yellow.

DIRECTIONS FOR USE: GH
Fill test tube to the indicated line with aquarium water. 
Holding the test solution bottle vertically, add the GH solution one drop at a time.
Be sure to count the number of drops being added.
Cap the test tube and invert several times after each drop.
The test is completed when the water in the test tube, after having been shaken, turns from orange to green.
The KH is determined by the number of drops of test solution that must be added to turn the water in the test tube bright green.
