Colombo Aqua GH Test – GH Test for Freshwater Aquarium
The Colombo GH test is designed to accurately measure the total hardness (GH) of water in freshwater aquariums and garden ponds. GH represents the total amount of dissolved minerals, primarily calcium and magnesium, which are essential for fish health and the growth of aquatic plants.
This drop test is reliable, easy to use, and perfectly suited for regular monitoring of water parameters, both when starting an aquarium and for routine maintenance.
Features
- Test type: colorimetric drop test
- Measures total hardness (GH) in °DH
- Up to 40 tests per kit
- Suitable for freshwater aquariums and ponds
Advantages
- Accurate and reproducible GH measurement
- Easy reading thanks to color change
- Quick use with illustrated instructions
- Economical solution for regular monitoring
Why Measure GH
Total hardness directly influences the well-being of fish and the development of plants. An appropriate GH promotes stable water, limits certain imbalances, and contributes to water clarity. Incorrect values can cause stress in fish or slow plant growth.
Instructions for Use
- Collect 5 ml of aquarium water in a clean test tube
- Add 1 drop of GH reagent and shake the test tube
- The sample normally turns red; if it turns green, the GH is below 1°DH
- Then add drops one by one, shaking after each addition
- When the color permanently changes from red to green, stop the test
The total number of drops added directly corresponds to the GH value in °DH. For example, 4 drops equal a GH of 4°DH.
Recommendations
It is recommended to test GH regularly, especially when introducing new fish, making significant water changes, or starting an aquarium. A monthly check is generally sufficient for a stabilized tank.
