In order to make the fish tank have a suitable temperature and the healthy growth of the fish, the regulation of the fish tank temperature is also a problem that we need to pay attention to. Many people think that the purpose of heating is to eliminate bacteria by raising the temperature. This understanding is completely wrong. . Because most pathogenic bacteria are resistant to high temperatures, their optimal growth temperature is generally around 37 degC, and the upper limit of the fish tank’s temperature rise generally does not exceed 35 degC. This temperature is the optimal temperature for bacteria to reproduce and will not cause disease at all. Bacteria cause harm. Not only does the temperature rise can not have any sterilization effect, but as the temperature increases, the pathogenic bacteria multiply and the toxicity increases and the water quality deteriorates.
1. The principle of Heating
To understand the true purpose of warming up, one must understand the fish’s immune system. Fish are temperature-changing animals. This physiological characteristic determines that the fish does not have the ability to maintain a constant body temperature. The body temperature of most fish is the same as the ambient temperature. The immune system of fish is closely related to temperature. In the low temperature state, the immune function will be weakened, which makes it easier to cause the death of the fish. When a disease invades, the fish themselves will show a “fever” symptom, which indicates that they want the water temperature to rise.
The real purpose of heating is to stimulate the fish’s immune system and increase the fish’s metabolism to fight against the invasion of pathogenic toxins, rather than relying on the three to five degrees of heating to directly kill bacteria. Of course, there are special cases in everything. For example, the small melon worm with white spot disease is directly killed by heating up. In terms of disease treatment, the principle of taking the lesser of the two evils should be observed. Although warming may cause bacteria to multiply and destroy water quality, warming can strengthen the fish’s immune defense ability and strengthen the fish’s physique to resist diseases. For diseased fish This is crucial.
2. The correct way to heat up
The reasonable temperature range should be 3-6 degC higher than the original tank water. Depending on the fish species, this range is about 30-34 degC. It is advisable to increase the temperature by 2-3 degC every day, as the temperature rises too fast and will cause discomfort to the fish. The temperature rise must be matched with large oxygen, and an adequate supply of oxygen must be ensured. Because the respiration of fish will be strengthened after the temperature rises, the reproduction of bacteria will be accelerated, and the oxygen demand will increase. The temperature rise should be used with salt to reduce the burden on the fish infiltration system.
There are several specific methods:
1. Heating rod: Advantages: The temperature can be controlled, the operation is convenient, and the heating effect is better. Disadvantages: some heating rods are too powerful and consume electricity
2. Regularly heating water into the tank: Advantages: The temperature can be controlled, and the water in the tank is not directly heated, which is relatively safe. Disadvantages: Inconvenient operation, easy to scare fish.
3. Put the bottle with hot water into the tank: Advantages: safe, and there will be no excessive temperature. Disadvantages: inconvenient, need to be replaced regularly, and the heating speed is relatively slow.
From the perspective of safety and convenience, it is recommended that aquarium fish lovers choose the combination of heating rod and thermostat. This double protection can effectively prevent the temperature from being too high and the death of fish during the heating process.
