Salifert KH/Alk Test Kit – Carbonate Hardness & Alkalinity, 100-200 Tests

Precision you can rely on for marine aquariums

The Salifert KH/Alk Test Kit is designed for hobbyists and professionals who regularly monitor carbonate hardness (KH) and total alkalinity (ALK) in saltwater and reef systems. Accurate alkalinity management supports stable pH swings, healthier corals, and consistent water chemistry without guesswork. The kit provides clear color indicators and a proven titration process you can perform with standard lab equipment at home or in a shop setting.

Why monitor KH and Alkalinity

KH and alkalinity influence how your tank buffers pH against daily changes, helping you maintain a comfortable environment for photosynthetic corals, fish, and invertebrates. Regular testing helps you track responses to dosing, water changes, and feeding routines. While results do not guarantee specific outcomes, they guide informed decisions for balancing your aquarium chemistry over time.

What to expect from the Salifert kit

• Dedicated tests for carbonate hardness and total alkalinity in one compact kit
• Clear, color-changing indicators that make readings straightforward
• Reliable reagents and a simple titration method designed for repeatable results

Ideal use cases

• Reef aquariums where stable alkalinity supports coral growth and coloration
• Saltwater tanks that experience regular dosing or water changes
• Educational setups or hobbyists building a routine for routine water testing

Tips for best results

Test at a consistent temperature and follow the step-by-step instructions. Use fresh reagents and compare colors against the provided reference color chart. Regular testing helps you observe trends over weeks and months rather than relying on single readings.
