Monitors the water values in aquariums simply and reliably. Determines: pH value, carbonate hardness, CO2 direct, iron, magnesium freshwater, potassium, phosphate, silicate and nitrate
Add the reagents to the water samples, compare on the colour chart, read off the values and check the analysis sheet to see which actions are recommended, if any
Comparator system takes the inherent water colouring into account (compensating it)
Contains a childproof reagent bottle in a waterproof plastic case. Refill reagents are separately available
Package contents: 1 test case incl. 22 reagents, 12 glass vials, 1 special potassium cuvette, 2 syringes, 3 measuring spoons, thermometer, comparator block, 2 plastic cuvettes, colour charts, pen, report sheets, operating instructions

Healthy aquariums with conditions close to nature
The right water values depend 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 the relevant water values quickly, easily and very precisely.

The following tests are available:
pH test: water acidity from 3.0 to 10
pH test: water acidity from 6.0 to 7.6
pH test: water acidity from 7.4 to 9.0
O2 test: determines the oxygen content
CO2 test: determines the carbon dioxide content for thriving plant growth
GH test: determines the general hardness
KH test: pH stability of the water (carbonate hardness)
PO4 test: determines the phosphate content (reason for algae growth and plant nutrient)
Test NH4 / NH3: identifies non-toxic ammonium, uses table to determine any toxic ammonia
NO2 test: determines nitrogen compound nitrite, which is toxic for the fish
NO3 test: determines the nitrate content (reason for algae growth and plant nutrient)
Fe test: determines the iron content to monitor fertilisation
Cu Test: heavy metal deadly for invertebrates. Also important for adjusting the dose of therapeutic medications
SiO2 test: determines the silicates (silicic acid), which cause diatoms

To determine the CO2 content you just need to measure the pH and KH values. These two values will give you the CO2 content in the water, which then can be referenced from the enclosed table.
With our research department and our worldwide expeditions into animal habitats we are continually setting new standards with our product innovations.

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