Dupla Products & Systems (Germany)

Analysis System

A permanent control of the water conditions helps you to become aware of any dangers for fish and plants and to take counter measures in time (diagnosis and therapy).

Trouble free care of fish and platns will allow the aquarist to enjoy the aquarium much more. Problems however will cause frustration and sometimes end with abandoning the aquarium hobby.

Furthermore, involvement with water analysis, gives you a heightened sensitivity for the water medium and a better understanding of any reports regarding qualities of our natural waters.

Dupla offers a wide range of analysis products for this purpose.
