Tetra Test KH

The Tetra KH Test kit measures overall hardness reliably and precisely. The general and carbonate hardness (GH + KH) are all linked and can influence various other aquarium parameters, most notably pH. Aquarium inhabitants such as fish react very sensitively to excessive changes in the pH value, which impacts their well-being. The general hardness affects the vital functions of fish, while the carbonate hardness has a direct influence on the stability of the pH value (pH buffer). The optimum carbonate hardness level for freshwater is 3 - 10 °dH, and for Marine is 8 - 10 °dH.

  • Suitable for all freshwater and marine aquarium
  • Excellent long-term stability
  • Measures overall hardness (KH)
