Frequently Asked Questions
What are GH and KH in aquarium water?expand_more
GH, or General Hardness, measures the total concentration of dissolved minerals, primarily calcium and magnesium, in your aquarium water. KH, or Carbonate Hardness, measures the water's alkalinity, which is its capacity to resist changes in pH. Both are critical for fish health, mimicking their natural habitats and preventing stress.
How often should I test GH and KH?expand_more
Our team recommends testing GH and KH weekly for stable freshwater aquariums. You should also test whenever you notice fish stress, observe plant health issues, or after performing significant water changes. Consistent monitoring helps catch problems before they escalate.
Is the API GH & KH TEST KIT easy to use?expand_more
Yes, the API GH & KH TEST KIT is designed for ease of use. It includes simple colour-coded instructions, test tubes, and solutions. By comparing the colour change of the water sample to a provided chart, you can accurately determine your water's GH and KH levels with minimal experience.
Why is KH important for aquarium pH?expand_more
KH, or alkalinity, acts as a buffer in your aquarium water. This means it helps to neutralise acids and prevent rapid, drastic drops in pH. A stable pH is vital for the health and well-being of most freshwater fish and invertebrates, preventing stress and ensuring a consistent environment.
Can this kit be used for saltwater aquariums?expand_more
No, this specific API GH & KH TEST KIT is designed exclusively for freshwater aquariums. Water parameters and their importance differ significantly between freshwater and saltwater environments. For saltwater tanks, you would require a specialised saltwater test kit.
What does it mean if my GH is too low?expand_more
If your GH is too low, it indicates low levels of essential dissolved minerals like calcium and magnesium. This can stress fish, particularly those adapted to harder water, and can also negatively impact the biological filter's efficiency. It may require adding mineral supplements or using harder source water.
How do I interpret the colour card in the test kit?expand_more
The colour card provided with the API GH & KH TEST KIT serves as your reference guide. After adding the specified number of drops of testing solution to your water sample in the test tube, you will swirl and observe the colour. You then compare this resulting colour to the shades on the card to determine the corresponding GH or KH value.
