Healthy aquariums with conditions close to nature The right water values are dependent on the fish stock, any algae or corals in the aquarium. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium. To maintain a healthy aquarium with conditions close to nature it is important to check and adapt the water values regularly.

For each water analysis JBL provides water tests in the form of quick tests or colour change tests. These determine a certain value or several values in one go. With these water tests you can recognise algae problems and negative nitrate, nitrite, potassium, magnesium values etc.

Why test?
Calcium helps to build up the structural substance of corals. A too low calcium level in the marine aquarium affects the growth of corals and impairs the invertebrates’ life functions (affects fish too!).

Recommended calcium levels:
Freshwater aquarium (community aquarium): calcium is part of the general hardness and present in much smaller quantities than in the marine water. That’s why the test doesn’t indicate anything in freshwater.
Marine Aquarium: 390-440 mg/l

You can analyse the water values you have measured in the JBL Online Laboratory free of charge and receive recommendations.
