Nitrifying bacteria are very delicate and have very strict requirements on PH value and temperature.

Nitrifying bacteria are attached to the surface of objects and can also play a role directly in the water body.

To understand how to select filter media, we must first understand how the filter media cultivates nitrifying bacteria.

First of all, when observed under an electron microscope, it will be found that most of the nitrifying bacteria are rod-shaped, and the nitrifying bacteria in water all have flagella that can swim. Swim in the water. The nitrifying bacteria that have been swimming in the water all the time cannot carry out nitrification, and nitrification must wait until the nitrifying bacteria attach to the solid surface.

As long as they are attached to a solid surface, they secrete a sticky substance that sticks themselves to the solid surface. As nitrifying bacteria multiply and increase in number, groups of nitrifying bacteria stick to each other, forming a biochemical film on the solid surface.

In other words, from the perspective of the characteristics of nitrifying bacteria, the filter material should have the following two requirements:

1. With a large surface area and voids, more nitrifying bacteria can be attached to the surface to reproduce;

2. The water permeability is better, and the nitrifying bacteria attached to the solid will not move, so the ammonia needs to be brought over by the water flow.

AC filter material is fast in cultivating bacteria and has a large amount of bacteria. If you are interested, please contact me!
