Description
The Salifert Alkalinity Marine Water Test Kit is a device that can be used to measure the alkalinity of marine water. Alkalinity is a measure of the amount of carbonate present in a water sample, and is important because it helps to stabilize the pH of the water. The Salifert Alkalinity Marine Water Test Kit can measure alkalinity in steps of 0.1 meq/L or 0.3 dKH, making it a suitable device for detecting small changes. The Salifert Alkalinity Marine Water Test Kit can measure alkalinity in a range of 2.7 meq/L to 7.5 dKH, which is similar to the alkalinity of water in the state of New South Wales. The Salifert Alkalinity Marine Water Test Kit is capable of measuring up to 200 measurements, making it a suitable device for monitoring the alkalinity of a marine environment.
Salifert Alkalinity (KH) Marine Water Test Kit
Calcium alone cannot form the skeletal material of corals and allow calcareous algae to grow. Some other substances are needed as well. A few other constituents are carbonate and bicarbonate. These two substances also have a major impact on the stabilization of the
pH in the proper range of 8.1 8.4. Such stabilization is also called buffering.
The total carbonate and bicarbonate concentration is also called carbonate alkalinity or carbonate hardness. The only difference between alkalinity and carbonate hardness is a conversion factor.
NSW has an alkalinity of approx. 2.7 meq/L or approx. 7.5 dKH when expressed as carbonate hardness.
For a stable system, the alkalinity or carbonate hardness should have a value similar to NSW or slightly higher and should preferably not fluctuate by more than 5%. This means a maximum fluctuation of 0.14 meq/L or 0.4 dKH.
Therefore an alkalinity test kit should be capable of measuring in steps smaller than 0.14 meq/L.
Conclusion:
Since the major buffer components used for coral and calcareous algae growth are bicarbonate and carbonate, they should be added to correct any decrease in alkalinity or carbonate hardness.
A properly formulated buffer should function in such a way that the corrective measures result in a long-lasting effect and should not upset the pH of the system. The alkalinity or carbonate hardness should be kept as stable as possible requiring highly sensitive and accurate means for testing.
The Salifert KH/Alk test is very straightforward. Itmeasures in sufficient small steps of 0.1 meq/L or 0.3 dKHwith a sharp color change.This makes the detection of important yet small changes possible.
The kit can perform approx. 100 - 200 measurements
