Tetra Pond Test 7in1

Tetra Pond Test 7in1 enables you to quickly and reliably determine the seven most important water values in ornamental ponds in one simple step: dip a test strip into the water, swirl it for about two seconds and tap off any excess water. Read off the most important information about the water values only one minute later. The colour chart on the tin of the test strips can be used to evaluate whether the water parameters are within the safe range to maintain a biological balance for fish, plants and microorganisms in your ornamental pond. You can find the exact limit values ​​and possible countermeasures in the enclosed instructions. To guarantee the function of the test strips do not touch the test fields or hold them under flowing water. The latest addition in Tetra Pond Test 7in1 determines the level of carbon dioxide (CO2) in the pond water. CO2 is especially required for your pond plants to thrive. Furthermore the pH, general and carbonate hardness (GH + KH), nitrite (NO2-), nitrate (NO3-) as well as chlorine (Cl2) in the garden pond water are measured. Pond inhabitants react very sensitively to excessive changes in the pH value, which impacts their well-being. The general hardness affects the vital functions of fish, while the carbonate hardness has a direct influence on the stability of the pH value (pH buffer). To stabilise the pH and KH values Tetra recommends the Tetra Pond WaterStabiliser. The Tetra Pond Test 7in1 also measures the nitrite and nitrate values of the pond water. Nitrite is extremely harmful for the biological balance in your pond, even in very low concentrations, and should not be detectable in the water. Nitrate is a nutrient that helps plants to grow. However, excessively high levels of NO3- can be harmful to fish and promote excessive algae growth. Chlorine may also be present in the water as it is often contained in tap water. Just like nitrite, chlorine should not be detectable in the pond water and always be treated with Tetra Pond AquaSafe.
