Salifert KH/ALK Profi Test Kit – Accurate Carbonate Hardness Testing

Precision Alkalinity & Carbonate Hardness Measurement for Reef Aquariums

Maintaining stable alkalinity (KH) is crucial for coral growth, pH stability, and the health of your reef aquarium. The Salifert KH/ALK Profi Test Kit offers highly accurate measurements in 0.1 meq/L (0.3 dKH) steps, allowing detection of even the smallest but important changes.

Carbonate and bicarbonate are essential for the formation of coral skeletons and the growth of calcareous algae. They also play a major role in buffering your aquarium’s pH, keeping it within the optimal range of 8.1–8.4. With natural seawater alkalinity at approx. 2.7 meq/L (7.5 dKH), this kit helps ensure your reef maintains stable and healthy conditions.
