Tetra Test 6-in-1 Strips Aquarium to Test 6 Essential Water Quality Parameters in Less Than 60 Seconds, Pack of 25

• Tetra Test 6-in-1 to check the six most important aquarium water values in one step
• Measures the pH, general and carbonate hardness (GH + KH), nitrite (NO2-), nitrate (NO3-), and chlorine (Cl2)
• Dip the test strips into the water, swirl them in the water for one or two seconds, shake off any excess water and read off the most important information about the water values just 60 seconds later
• pH - The pH value of the water indicates the acid or base concentration that is important for the health of the fish. A pH value between 6.5 and 8.5 is tolerated by every freshwater fish species
• KH - KH acts as a pH-buffer and the favourable KH values are between 3 ° and 10 °dH

Product Description Tetra Test 6-in-1 Strips Aquarium to Test 6 Essential Water Quality Parameters in Less Than 60 Seconds, Pack of 25. Directions Quick and easy checking of water quality. With the Tetra Test 6-in-1, you can check in seconds whether the aquarium water is in optimal condition. Pull the test strips through the water a few times, shake off excess water, compare the chlorine test section with the reference scale and after 60 seconds. compare the remaining test sections. Determines pH, carbonate and total hardness (KH+GH), nitrite (NO2), nitrate (NO3) and chlorine (Cl2) content. pH - The pH value provides information about the acidity or base content of the water important for the health of the fish. A pH value between 6.5 and 8.5 is ideal. KH - The carbonate hardness ensures a constant pH value. As a rule, a hardness between 3° and 10° dH is recommended.
