Description
Ideal for salt water aquariums and coral reef tanks. Designed exclusively for saltwater aquariums, the HI-772 checker offers a quick, easy and highly accurate method of measuring alkalinity in degrees of calcium hardness, commonly abbreviated as dKH.
Alkalinity helps to maintain a stable pH, a vital factor for most aquatic life. Corals also need an adequate level of alkalinity in order to support healthy growth: if levels are too low, corals cannot precipitate and form their skeletons; if levels fluctuate too much or too quickly, growth can become impaired.
The more precise and stable the levels, the better the results. With regular, precise monitoring, fluctuations in levels can be quickly corrected, giving your corals the best chance of success.

Why is Alkalinity important in aquariums?
Alkalinity, also known as carbonate hardness, is a crucial parameter to maintain in aquariums. It refers to the ability of water to neutralize acids and is measured in degrees of carbonate hardness (dKH) or parts per million (ppm).
Here are a few reasons why maintaining proper alkalinity is important in aquariums:
- Stability: Alkalinity plays a significant role in maintaining stable pH levels in aquariums. If the alkalinity is too low, pH levels can fluctuate rapidly, leading to stress and potential harm to aquatic life. On the other hand, high alkalinity can cause pH levels to remain too high, which can be harmful to some species of fish and corals.
- Calcium and Magnesium Availability: Alkalinity affects the availability of calcium and magnesium, which are essential for the growth and development of corals and other invertebrates. Low alkalinity levels can result in a decrease in calcium and magnesium levels, leading to poor growth and health of corals.
- Buffering Capacity: Alkalinity acts as a buffer, helping to stabilize water chemistry and prevent sudden changes in pH levels. A stable alkalinity level ensures that the water chemistry remains within a safe and healthy range for aquatic life.
Overall, maintaining the proper alkalinity level is crucial for the health and well-being of aquatic life in aquariums. The Hanna Checker HI-772 Alkalinity DKH is a reliable tool that can help aquarium owners accurately measure and monitor alkalinity levels, ensuring a stable and healthy environment for their aquatic pets.

Interpreting the Results
When using the Hanna Checker HI-772 Alkalinity DKH, it is important to know how to interpret the results. The device measures alkalinity in degrees of carbonate hardness (dKH), which is the standard unit of measurement for alkalinity in saltwater aquariums. The results will indicate the level of alkalinity in the aquarium water.
A healthy saltwater aquarium should have an alkalinity level between 7 and 12 dKH. If the alkalinity level falls below 7 dKH, it could lead to pH instability, which can be harmful to the aquatic life. On the other hand, if the alkalinity level is too high, it can cause precipitation of calcium and other minerals, leading to cloudy water and other issues.
The Hanna Checker HI-772 Alkalinity DKH provides a simple and accurate way to measure alkalinity levels in saltwater aquariums. The device uses a colorimetric method to determine the concentration of carbonate ions in the water sample. The results are displayed in dKH on the device’s digital screen.
To interpret the results, compare the measured value to the desired range of 7-12 dKH. If the measured value is within this range, the aquarium’s alkalinity is considered to be at a healthy level. If the measured value is outside this range, adjustments to the water chemistry may be necessary.
Some common ways to adjust alkalinity levels include adding buffer solutions or performing partial water changes. It is important to follow the manufacturer’s instructions carefully when adding any supplements or chemicals to the aquarium water.
In conclusion, interpreting the results of the Hanna Checker HI-772 Alkalinity DKH is a crucial step in maintaining a healthy saltwater aquarium. By keeping the alkalinity level within the desired range, aquarium owners can ensure the well-being of their aquatic pets and the overall health of the aquarium environment.
