(KH) Carbonate Hardness should be tested on a regular basis as it can fluctuate over time and negatively impact the pH balance of aquarium water
(GH) General Hardness testing is beneficial to creating ideal water hardness conditions based on the origins of tropical fish species
Testing KH every 48 hours is essential in some densely populated marine reef aquariums
Fish & nitrifying bacteria excrete CO2, leading to the formation of carbonic acid, which depletes KH values, especially in heavily stocked aquariums
KH testing is ideal for use in fresh and saltwater aquariums; GH testing is ideal for use in freshwater aquariums
Description (KH) Carbonate Hardness. Routine testing will quickly reveal fast depletionof KH levels in marine reef aquariums, which can result in poor plant growth and is a major factor in the reproduction of fish requiring softer water conditions. The denser the population of fish and plants, the quicker the erosion of KH values. KH should be tested on a regular basis as it can fluctuate over time and negatively impact the pH balance of aquarium water. (GH) General Hardness testing is needed to determine if calcium and magnesium levels are being maintained for fish. Ideal for testing before adding new fish to an established aquarium. Made in Canada, Fluval Test Kits accurately measure water parameters to help you maintain a balanced and healthy environment for your fish and plant life. It’s important to always test your source water as it may contain pollutants hazardous to your aquarium.
