This Nutrafin test kit measures the carbonate hardness (KH) and total hardness (GH) of water in freshwater and saltwater aquariums.
Since carbonate hardness can vary greatly over time and thus affect the pH level of aquarium water, it is important to test it periodically. Regular analyzes will reveal sudden decreases in carbonate hardness in saltwater aquariums.
- It may be essential to test every 48 hours in densely populated saltwater aquariums. Indeed, the denser the population of fish and plants, the faster the carbonate hardness decreases. Such densely populated aquariums often require the addition of alkalinity reactors to meet the needs of their inhabitants.
- Hardness plays a considerable role in the reproduction of fish requiring soft water conditions.
- Fish and nitrifying bacteria give off carbon dioxide, which eventually leads to the formation of carbonic acid. In densely populated aquariums, carbonic acid is responsible for the rapid decrease in carbonate hardness.
- Low carbonate hardness can inhibit the growth of aquatic plants.
- This analysis is suitable for both freshwater and saltwater aquariums.
Total hardness analysis is essential in creating ideal aquatic conditions for kept species of tropical fish. For freshwater aquariums, it is recommended not to keep hardwater tropical fish and freshwater tropical fish in the same aquarium. Additionally, it is strongly recommended that you know the total hardness requirements of tropical fish before attempting to breed any.
- It is important to test the total hardness of the water before adding new fish to a fully functioning aquarium.
- This test is suitable for freshwater aquariums only.
