Tetra Test 7in1 enables you to quickly and reliably determine the seven most important water values in your aquarium in three simple steps. Evaluate the level of pH, carbonate hardness (KH), general hardness (GH), nitrite (NO2-), nitrate (NO3-), chlorine (Cl2) and carbon dioxide (CO2).
Application Suggestion Easy testing in three steps Dip the test strip into the aquarium water and move 2-3 times. Shake off the excess liquid. Wait approx. 60 seconds and compare the test fields with the colour charts. Caution: Do not touch the test fields or hold them under running water!
