For the determination of the phosphate concentration in fresh and seawater.
Phosphates are an important food component of all plants and absolutely necessary for the metabolism of every living cell. If the plants do not take up enough phosphate, th...
For the determination of the nitrite and nitrate concentration in freshwater and seawater.
Nitrite (NO2-) is the intermediate stage of the aerobic nitrification and is highly toxic for fish and invertebrates. A too high concentration of nitr...
For the determination of the carbonate hardness or the alkalinity in seawater.
The carbonate hardness or alkalinity corresponds to the buffer capacity of the aquarium water and therefore determines the stability of the pH-value in the water. With thes...
For measuring magnesium and calcium concentrations in seawater.
Magnesium and calcium concentrations and the ratio between these two elements are constantly changing in marine aquariums due to assimilation into the skeletons of corals and coralline a...
Tropic Marin Calcium-Test For the determination of the calcium concentration in saltwater.Calcium is one of the most important components of saltwater and largely determines the growth rate of organisms, which form calcareous skeletons like, for example stony corals and calcareous algae. In the s...
