Detailed Description

Carbonate Hardness (KH) levels need to be tested on a regular basis because they fluctuate over time and can negatively impact the pH balance of the aquarium water. Low Carbonate Hardness will result in poor plant growth. Testing for General Hardness (GH) should be done to determine if the levels of Calcium (Ca) and Magnesium (Mg) are optimal for specific species of fish.
