NT Labs Aquarium GH and KH Hardness Test Kit

NT Labs 80 Contains Freshwater Aquarium GH and KH Hardness Test Kit

Tests tap water and freshwater aquariums for general hardness (Gh) and carbonate hardness (Kh). Helps detect stress on fish caused by rapid ph shifts, which result from low KH levels, and helps aquarists affect the natural habitat of their fish.

How to use it?

  • Ensure the test tube is clean.
  • Take a 5 ml sample of water into the test tube.
  • Take the KH reagent and add one drop, mix, and the water sample should turn pale blue.
  • Keep adding drops, one by one (remember to count the drops), mixing between drops, until the blue color turns to yellow. The number of drops, including the first drop, needed to bring about the color change is equal to the KH value in dKH. Should the first drop of reagent turn the sample yellow then the KH value is below 1 dKH – this is extremely dangerous for fish.

GH in detail:
What is the correct GH level?

This test kit measures GH in dGH (where one degree = 17.8 ppm as CaCO3). The correct GH depends on the type of fish being kept. For soft water species, aim for a GH of around 3 to 6 dGH, while for hard water species, 10 to 15 dGH is the correct range.

What do I do if the GH level is wrong?
Test the GH of your tap water. The GH of tap water is determined by whether you live in a hard or soft water area. If the water is too hard for the fish being kept, alternative waters can be used, such as reverse osmosis water, to lower the GH. To increase the GH for aquarium fish, calcium carbonate rocks (like ocean rock) can be used to provide a continual source of GH minerals.

Description

What is KH?
KH, also known as “total alkalinity” or “carbonate hardness”, is a measure of the buffering capacity of the water in your aquarium. The buffering capacity refers to how well it can resist changes in pH.

What is GH?
General Hardness is a measure of the total amount of minerals dissolved in the water. Water hardness lies on a spectrum between ‘soft water’ or ‘hard water’ depending on the amount of dissolved minerals: the more minerals present, the greater the hardness. Hard water is responsible for the build-up of limescale.

KH in detail:
What is the correct KH level?

This test kit measures KH in dKH (where one dKH = 17.8 ppm as CaCO3). It is essential to maintain a minimum KH level of at least 4 dKH at all times. A KH of between 6 and 8 dKH is more desirable.

What do I do if the KH level is wrong?
Check the KH level of your tap water. If the level is above 6 dKH, then regular water changes should keep the KH value in the aquarium topped up at a reasonable level. If the KH value of your tap water is below 6 dKH, you will need to add a KH buffer such as KH Up – pH Stabiliser to your aquarium/pond.
