Praktikus kálcium teszt a német JBL-től. - Javasolt érték tengervízi
akváriumokban: Ca: 400-440 mg/l - Professzionális teszt a kalciumtartalom pontos
meghatározására minden tengeri akváriumban.. - A túl alacsony kalcium-értékek
hátráltatják a korallok növekedését. - A teszt 20 mg-os lépésenként jelzi a
kalcium-értéket. 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
