Product Description Feature: Test items and scope: Hardness hardness test range 0~1000 Free chlorine residual chlorine test range 0-20 Nitrate nitrate test range 0~240 Nitrite nitrite test range 0-10 Carbonate Root Carbonate Root Test Paper 0-180 PH test range 6.2-8.4 Description of detection elements 1. Hardness Hardness refers to the content of calcium and magnesium ions in the water. If the hardness of the fish pond or water tank is too high, soft water should be added; if it is too low, tap water should be added to adjust. 2. Residual chlorine Tap water contains residual chlorine, which can damage the gills and skin of fish. 3. Nitrate Nitrite Too high is harmful to fish 4.PH The most suitable environment for fish is weak alkaline environment, freshwater aquaculture generally requires 6.5-8.5, and the most suitable range is between 7.5-8. Too high or too low PH is not good for fish growth. If the pH value is less than 4.4, the fish mortality rate can reach 7% to 20%. When the pH value is higher than 10.4, the mortality rate can reach 20% to 85%. When the pH value is higher than 10.6, it can cause all deaths. When the pH is only lower than 6.5, the oxygen-carrying ability of the blood of the animal will be reduced, resulting in physiological hypoxia, a decline in the metabolic function, and a decline in the immune function; Breathing ability and mass death.
