Healthy aquariums with conditions close to nature The right water values are dependent on the fish stock and the plants in the aquarium. Even if the water looks clear it can be contaminated. Bad values can cause diseases or algae in the aquarium. To maintain a healthy aquarium with conditions close to nature it is important to check and adapt the water values regularly. With JBL water tests you can determine all relevant water values quickly, easily and very precisely.
The following tests are available for marine water: pH test: acidity of the water from 3.0 to 10 pH test: acidity of the water from 6.0 to 7.6 pH test: acidity of the water from 7.4 to 9.0 O2 test: determination of the oxygen content KH test: pH stability of the water (carbonate hardness) PO4 test: determination of the phosphate content (reason for algae growth and plant nutrient) Test NH4 / NH3: indication of non-toxic ammonium, determination of the toxic ammonia using table NO2 test: determination of nitrogen compound nitrite, which is toxic for the fish NO3-Test: determination of the nitrate content (reason for algae growth and plant nutrient) Cu Test: heavy metal deadly for invertebrates. Also important for adjusting the therapeutic dose of medications SiO2 test: determination of the silicates (silicic acid) as cause for diatoms Ca test: determination of the calcium content in marine aquariums. Should be between 400 and 440 mg/l for healthy coral growth Mg/Ca test: determination of magnesium and calcium content in marine water aquariums. The magnesium content should be between 1200 and 1600 mg/l. During the procedure, first the Mg content is tested and then the Ca content. Subsequently, the value of the Ca content is subtracted from the Mg content and this is then the actual Mg content of the water.
