The NT Labs Hardness Test Kit is an indispensable tool for aquarium enthusiasts, providing accurate measurements of both carbonate hardness (KH) and general hardness (GH). KH measures the buffering capacity of the water, which helps stabilize pH levels, while GH indicates the total amount of dissolved minerals, affecting water softness or hardness. This kit helps ensure your aquarium maintains optimal water conditions, crucial for the health of your fish and plants.

Why Should I Test for Hardness?

• KH (Carbonate Hardness): KH is crucial for maintaining a stable pH in your aquarium. It measures the water's ability to buffer against pH changes, preventing sudden fluctuations that can stress or harm fish. A KH level between 6 and 8 dKH is desirable, with a minimum of 4 dKH to ensure adequate buffering capacity.
• GH (General Hardness): GH measures the concentration of minerals like calcium and magnesium in the water. The correct GH level varies depending on the fish species. Soft water species prefer a GH of around 3 to 6 dGH, while hard water species thrive at levels between 10 and 15 dGH. Maintaining the appropriate GH is essential for the physiological health of your aquarium's inhabitants.
