API Turtle GH and KH Test Kit Water Hardness Testing

The API® GH & KH Test Kit accurately measures general hardness (GH) and carbonate hardness (KH) in turtle habitats, pond water, and aquariums. Both parameters matter for aquatic health — GH reflects dissolved calcium and magnesium, KH buffers against pH swings.

What It Measures

• GH (General Hardness) — total dissolved calcium and magnesium
• KH (Carbonate Hardness) — carbonate and bicarbonate buffering capacity

Key Features

• Liquid reagent kit — drop-by-drop titration
• Accurate results for turtle, aquarium, and pond water
• Includes test tubes, reagents, and reference chart
• Each bottle tests dozens of water samples
