The API Carbonate Hardness (KH) Test Kit is an essential tool for aquarium enthusiasts, designed to measure the carbonate hardness of water in both freshwater and saltwater aquariums.
Carbonate hardness, or KH, plays a crucial role in stabilizing pH levels, thereby ensuring a healthy environment for aquatic life.
Key Features:
Water Type Compatibility Designed for use in both freshwater and saltwater environments, making it versatile for a wide range of aquatic systems .
Complete Testing Kit Includes one reagent bottle, a glass test tube with cap, and a color chart plus clear instructions—ideal for weekly monitoring.
Easy-to-Use Drop Test Add 5 ml of aquarium water to the test tube, then titrate with reagent until the water shifts from blue to yellow, with each drop representing 1 dKH.
pH Stabilization Insights KH buffers aquarium pH; low KH can lead to rapid pH changes (“pH bounce”), while adequate KH supports coral growth and acidic stability.
Refill-Compatible Can be used to refill larger Master Test Kits when reagent runs low.
Recommended Testing Frequency Ideal for weekly monitoring, or whenever you suspect pH instability or water quality issues.
