Analysis System

Regular checks, particularly of the pH value, the nitrite content, and the carbonate hardness, but also the iron content and other important parameters, prevent the aquarium from coming apart at the seams without noticing. Compared with natural waters, the aquarium contains only a very small amount of water. Each value can slip from one extreme to the other in the shortest period of time. Yet the aquarium requires a high degree of stability and consistency. Therefore, Dupla offers a chemical analysis system as a diagnostic measure, based on which the correct therapy can be started, for examply by using the Dupla water treatment system.
