Water quality

Correct water quality is of great importance for the well-being of the animals and plants in the aquarium. Stress is also often the number one cause of death in fish and shrimp. Maintaining a healthy living environment can be done by testing the values of the aquarium water. With the right resources, conditions can be optimized so that all inhabitants feel at home in the aquarium.
