normal circumstances, the ceramic ring does not need to be replaced unless it has been blocked, the water flow can not pass through, or the acid drop is serious, and the further reproduction of nitrifying bacteria needs to be curbed. Like the bacteria house, it is a biochemical filter material with a large number of holes on it, which is convenient for nitrifying bacteria to attach to it, so as to better establish the nitrification system.
the ceramic ring 1. Disinfection: Before using the ceramic ring, it must be disinfected, because its structure is porous, it is easy to carry some harmful substances, once it enters the water, it will even affect the health of fish. The method of disinfection is very simple, it can be soaked in potassium permanganate solution, and then washed and soaked in clean water to avoid drug residues.
2. Placement: The ceramic ring cannot be directly placed in the fish tank. It is usually placed in the filter bin and placed in the back. In this way, the incoming water flow is basically clear after physical filtration, and will not bring some dirt, thus affecting the growth and reproduction of nitrifying bacteria.
3. Bacteria culture: In order to accelerate the establishment of the nitrification system, proper bacteria culture is required. In the first month, nitrifying bacteria should be added once a week, and the lights should be turned off at the same time, because they are aerobic bacteria, do not like light, and are more likely to multiply in a dark environment.
