• Detects changes as small as 0.1 meq/L
• Helps maintain stable pH levels (8.1–8.4)
• Sharp and clear color endpoint for easy reading
• Ideal alkalinity target: ~2.8 meq/L
• Prevents alkalinity fluctuations beyond 5% tolerance
• Suitable for marine, freshwater & garden pond water
• Provides 50–100+ tests depending on usage
• Compatible with KH & alkalinity correction additives

The Salifert KH & Alkalinity Test 50T is a precision testing solution for aquarists who demand stability and consistency in their systems. By accurately monitoring carbonate hardness, this kit helps ensure optimal coral skeletal growth, strong buffering capacity, and long-term aquarium health. A must-have testing tool for every serious reef keeper at Reef freaks.
