1, prepare the attachment
Nitrifying bacteria need to attach to a substance to survive, so to prepare attachments for them, materials with large surface area and many holes are usually the most suitable, such as water beads, ceramic cups or sand, and the volume of attachments is preferably 20% of fish tank water.
Step 2 control the temperature
Nitrifying bacteria are very sensitive to temperature changes, so it is necessary to control the temperature between 5-35℃ during culture to ensure their metabolic activities. If the temperature is too high, nitrifying bacteria will be difficult to survive, and in serious cases, a large number of deaths will occur.
Step 3 increase oxygen
In order to improve the survival rate of nitrifying bacteria, it is necessary to increase the oxygen pump to produce a large amount of oxygen in the fish tank, and the culture time of nitrifying bacteria is more than 24 hours. In the meantime, try to avoid light, and the lights in the fish tank can be turned off.
4. Wild plants
Nitrifying bacteria can appear without special culture. Nitrifying bacteria will grow naturally in fish tanks under normal operation. Generally, it takes 1-2 weeks to cultivate mature nitrifying bacteria in fresh water and 1-2 months in seawater. If nitrifying bacteria are urgently needed, you can directly buy finished products in the market and put them in fish tanks.
Living environment of nitrifying bacteria
Nitrifying bacteria is an aerobic bacteria with adhesion function. I like living in biochemical balls, ceramic rings, bacteria houses and other places with gaps in water. Nitrifying bacteria can be attached to it to work and reproduce. The modified accessories must have enough water to flow through, and there must be no dead corners and anoxic areas before water can flow.
In addition, nitrifying bacteria belong to aerobic bacteria, and oxygen is indispensable for both work and reproduction, so the fish tank must keep enough oxygen to promote the reproduction of nitrifying bacteria. Nitrifying bacteria don't like direct sunlight, especially sunlight, so nitrifying bacteria like dark and cool environment.
The optimum temperature of nitrifying bacteria is about 25℃. If the temperature is too low, the activity will decrease. Only when the activity is the highest at 25℃, nitrifying bacteria can easily multiply rapidly.
