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.
Storage conditions and validity period
1.Storage conditions: Store at 2℃～30℃ in a dry place, protected from light (2℃～8℃).
2.Product validity period: Store in a dry place at 2°C to 30°C away from light, and the validity period is 24 months.
3.Validity period for opening the bottle: After opening, the cap of the cylinder should be sealed and stored in a dry place at 2°C to 30°C away from light. The validity period is 24 months.
Sample requirements
1.Take 5-10ml of the sample, and take the supernatant for testing after standing.
2.The test is carried out at room temperature around 25°C.
Testing method
1.Immerse the reaction area of the test strip in the solution to be tested for 1-2 seconds, take out the test strip, and drain off the excess water on it.
2.After 1 minute, compare the reaction area of the test strip with the color of the colorimetric card to determine the test value of the solution to be tested.
3.The colorimetric time should be controlled at about 60s, if the time is too long or too short, the reading will be affected.

【Precautions】
1. Do not touch the reaction end of the test strip when taking out the test strip, so as not to contaminate the test strip and affect the test results.
2. After taking out the required number of test strips, keep the remaining test strips sealed and protected from light.
3. The liquid to be tested should be kept as colorless or light-colored as possible. Before testing, the liquid with too dark color can be adsorbed with activated carbon for dehydration treatment. If the liquid to be tested is turbid, let it stand for a period of time, and then take the clear part for testing after precipitation.
