Fish farming is common in our lives, but if we want fish to live in safe and healthy water, water quality monitoring is essential to improve, this chapter water quality online monitoring equipment manufacturers to learn with you fish water quality monitoring problems.

Fish raise water first, if you want to fish raise well, water quality is very key!

We can judge the quality of water quality by looking and smelling, so it is necessary to master some basic water quality testing, such as: PH value, ammonia nitrogen, nitrite and other water quality parameters monitoring. Because food residues and biological excrement are decomposed into ammonia, and further oxidized to nitrite, nitrite is too high into the gill epithelial cells, and then the heme oxidation into heme, so that the red blood cells in the blood lose the ability to combine with oxygen. Because of this, fish disease and lack of oxygen can cause fish to lose their lives.

Method for Testing NO2-Nitrite

1.Put 1mL of water into the test tube with a syringe;

2.Put 1 spoonful of NO2 powder into the test tube and gently shake it for 20 seconds, then leave it for 3 minutes;

3.Put the open test tube on the white part of the color card, compare the colors, and read the corresponding nitrite value;

Although nitrite is highly toxic, it can be easily removed in several ways:

1.Change the water frequently;

2.Add appropriate filter devices and filter materials;

3.Add nitrifying bacteria.
