API GH & KH General & Carbonate Hardness Freshwater Aquarium Test Kit
Duplicate the natural habitat of your freshwater fish and plants and help prevent dangerous pH shifts with API's GH & KH Freshwater Aquarium Test Kit. Water hardness is the amount of dissolved mineral content in water and it comes in two types: general hardness (GH) and carbonate hardness (KH). KH levels can cause rapid and wide shifts in pH levels which can stress fish and cause illness or death. And high levels of GH can create unsightly, calcium crust to form in your aquarium including the hood and glass. To test, just fill a test tube with tank water and add the test drops. The KH value is determine by the amount of test solutions needed to the turn the test water bright yellow. The GH value is determined by the amount of reagent needed to turn the test water green. Then follow the instructions included to take appropriate actions.
Key Benefits- Monitors GH (general hardness) and KH (carbonate hardness) levels for a more natural habitat for your fish.
- Promotes a more natural habitat and is ideal for a planted aquarium.
- Helps prevent wide, abrupt pH level changes from low KH levels.
- Helps fight crusty calcium buildup on the hood and glass of the aquarium.
- Easy to use and comes with everything you need.

For Testing KH
-
Rinse a clean test tube with water to be tested.
-
Fill the test tube with 5 ml of water to be tested (to the line on the tube).
-
Holding the bottle vertically, add KH Test Solution, one drop at a time. Be sure to count the number of drops being added.
-
Cap the test tube and invert several times after each drop.
-
The test is completed when the water in the test tube, after having been shaken, turns from blue to yellow. If you have difficulty discerning the color after the first drop of test solution is added, remove the cap from the test tube and, while holding it over a white background, look down through the tube.
-
The KH value is determined by the number of drops of test solution that must be added to turn the water in the test tube bright yellow.

What is Carbonate Hardness (KH)?
Carbonate hardness, also known as alkalinity, is the measure of carbonate and bicarbonate concentrations dissolved in water. These minerals are present in municipal, well, and bottled water. The level of carbonate hardness in tap and bottled water depends on the source of the water and the treatment processes it has undergone. Carbonate hardness helps stabilize pH in the aquarium.
An aquarium with a low KH level will tend to be acidic. Aquariums with very low KH are subject to rapid pH shifts if not monitored carefully. Water with a high KH level usually has a high pH.
What is General Hardness (GH)?
General hardness is the measure of calcium and magnesium ion concentrations dissolved in water. These minerals are present in municipal, well, and bottled spring water. The level of general hardness in tap and bottled water depends on the source of the water and the treatment processes it has undergone. Hard water is high in calcium and magnesium, while soft water is low in these minerals.
