GH TEST – Reagent for Measuring Total Hardness in Freshwater Aquariums
The GH Test is an essential tool for monitoring general hardness (GH) in freshwater aquariums. GH, measured in degrees of German hardness (°dGH), indicates the concentration of dissolved calcium and magnesium salts, which are vital for the wellbeing of both fish and plants.
Maintaining proper GH levels helps ensure biological balance in the aquarium. Low hardness can negatively affect fish health and hinder plant growth, while excessively high hardness can lead to nutrient precipitation. The optimal GH value in freshwater tanks ranges from 7° to 12° GH, depending on the needs of the species kept.
This test is quick and easy to use, making it ideal for aquarists of all experience levels. Regular testing is recommended, particularly after water changes or system modifications, to maintain a stable and healthy environment.
Why choose the GH test:
Accurate measurement of total hardness (GH)
Essential for fish and plant health
User-friendly and reliable
Suitable for all freshwater aquariums
