The AquaLabs GH Test Kit provides accurate, easy-to-read measurements of General Hardness (GH), an important parameter for assessing calcium and magnesium levels in freshwater aquariums. Monitoring GH helps support healthy fish development, strong plant growth, and successful invertebrate moulting.

Designed exclusively for freshwater use, this kit is not suitable for saltwater aquariums.

Using high-precision liquid reagents, the test kit delivers clear and reliable results across a wide practical range, with two testing methods available to suit different needs:

Test Range:
0 – 500 ppm GH

Testing Options:
• Precision Test: Measures in 10 ppm increments (≈ 0.56 dGH) for detailed water analysis
• Quick Test: Measures in 25 ppm increments (≈ 1.4 dGH) for fast routine checks

Each kit contains sufficient reagent for repeated testing, making it ideal for both detailed diagnostics and ongoing aquarium maintenance.

Kit Includes:
• High-accuracy liquid GH reagents
• 5 mL glass test tube with secure cap
• Easy-to-read drop conversion chart
• Clear, step-by-step instructions

Ideal for freshwater aquariums, shrimp tanks, and planted systems, the AquaLabs GH Test Kit allows aquarists to fine-tune water hardness, prevent mineral deficiencies, and maintain optimal conditions for a healthy, thriving aquatic environment.
