Complete kit for permanent direct measurement of the CO2 content in aquariums
Kit containing:
- Long term test with suction holder
- Indicator fluid 10ml for approx. 90 measurements
- 3pcs. of TEST5in1 water test sticks for testing of carbonate hardness which is important for the CO2 fertilization
EHEIM LONG TERM TEST

Long term test application:
Add approx. 1ml aquarium water up to the marking of the filling level and 4 drops of indicator reagent in the CO2 endurance test unit and fix it in the aquarium at the pane using a suction cup. Compare the indicator color with color scale and read the value.

EHEIM TEST5in1

TEST5in1 water test determine the 5 most important water values at once:
- Nitrite (NO2)
- Nitrate (NO3)
- Total hardness (TH)
- Carbonate hardness (KH)
- Acidity (pH)
TEST5in1 application:
- Fully immerse the test strips in the water for 1 - 2 seconds
- Shake off any excess water and lay the test strips on a level surface
- Wait 60 seconds. Now compare the color of each test area to the color scale on the container. Look for the closest match to each color and read the measured value. Refer to the chart for recommended water values
