Jbl Pro Aquatest Easy 7in1 Ph Gh Kh No2 No3 Cl2 Co2

JBL PROAQUATEST EASY 7in1 50 pieces


Test strips for water analysis

Test strips for simultaneous determination of GH, KH, pH, NO2, NO3, Cl2 and CO2 values in aquariums


Quick and easy determination of the 7 most important values of aquarium water composition. Measurement of nitrate (NO2) and nitrite (NO3) content provides information about the functioning of purification processes. KH affects pH stabilisation. GH shows excess or deficiency of minerals in the water. The Cl2 value shows whether the water contains chlorine, which is harmful to fish, and the main nutrient for plants (CO2 content from the table).


The tests allow you to examine:

water pH

kH level

GH level (carbonate hardness)

nitrite (NO2) level

nitrate (NO3)

Chlorine Cl level

CO2 level from the table


The following values can be determined in a quick test:

Disinfectant in tap water: Chlorine test Water acidity: pH test from 6.4 to 9.0

Water stability: KH test from 0 to 20 °dKH

Total water hardness: GH test from 21 °dKH

Toxic nitrogen compound: NO2 from 0 to 10 mg/l

Cause of algae: NO3 from 0 to 250 mg/l

CO2 content: 0-239 mg/l


Easy to use:

Dip the test strips into the aquarium and move them around for 2-3 seconds. Remove the test strips from the water and hold them horizontally to allow the water to drip off. After 60 seconds, compare the values on the test strip with the colour scale on the packaging.

Store the test strips in a cool, dry place. Only remove the number of strips you need.

In the JBL Online Laboratory, you can analyse the measured water parameters free of charge and receive recommendations.
