JBL Marine Aquatest Lab (Short Dated)

With JBL water tests you can determine all relevant water values quickly, easily and very precisely.

Precise measurement of the following values come included in the kit -
pH test: acidity of the water from 7.4 to 9.0
KH test: pH stability of the water (carbonate hardness)
Ca test: most important macro-element for the growth of invertebrates
Mg test: important macro-element for the growth of invertebrates and calciferous red algae
Cu test: deadly heavy metal for invertebrates. Also important for setting the therapeutic dose of medications
NO2 test: toxic nitrogen compound
NO3 test: too high nitrate values cause unwanted algae growth
NH4 test: indication of non-toxic ammonium, determination of the toxic ammonia using table
PO4 test: high phosphate values lead to unwanted algae growth
SiO2 test: cause for diatoms
O2 test: basic requirement for fish and plants

You can analyze the water values you have measured in the JBL Online Laboratory free of charge and receive recommendations. The link for this is below.

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.

The following tests are the complete available stock 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.
