Salifert Freshwater Test General Hardness GH

Salifert Freshwater Test General Hardness GH for Optimal Water Chemistry

The Salifert Freshwater Test General Hardness (GH) is a professional-grade diagnostic tool designed to measure the concentration of dissolved calcium and magnesium in your aquarium. Because different species of fish, shrimp, and aquatic plants require specific mineral levels to maintain osmotic balance and health, monitoring GH is critical for long-term success.

This kit is particularly indispensable for advanced aquarists who utilize RO (Reverse Osmosis) water or remineralized water, where precise control over mineral additives is required. By utilizing a highly accurate colorimetric reaction, Salifert ensures that you can maintain the stability of your water parameters, specifically targeting the 8 to 12 dGH range recommended for most planted freshwater aquariums.
