💧 API GH & KH Test Kit | General & Carbonate Hardness Testing for Aquariums

📖 Overview The API GH & KH Test Kit is a reliable and accurate way to measure the general hardness (GH) and carbonate hardness (KH) of your aquarium water. GH indicates the amount of dissolved calcium and magnesium, while KH measures carbonate and bicarbonate levels that buffer pH. Together, these parameters are crucial for creating a stable, healthy environment for fish and plants.

Ideal for freshwater aquariums, this test kit helps aquarists better understand water chemistry, prevent harmful swings in pH, and maintain conditions that support species-specific needs.
