In the aquarium fish, there is a kind of common disease of saprolegniasis. Saprolegniasis is also called the white problem, the main pathogens are water mold and mildew, parasitic on fish and eggs on the wound, is a common disease. The main cause of the disease is fish injury, scale fall off and so on, causing the bacteria to invade the wound. At the same time, when fish are caught or transported, the fish is injured or parasites, which can infect the skin of the fish.
I. symptoms of water mildew
When the fish has been infected with the disease, it can not see any symptoms. But once the body is white, the hyphae have invaded the body's wound and spread into the space between the muscles. As the disease develops, the muscles of the affected areas decay, the appetite decays, and eventually dies.
Two. Disease of mildew
The disease can occur throughout the year. In order to prevent the occurrence of water mildew, we should pay attention to avoid damage to fish and parasites, as well as to put a small amount of salt in water to inhibit the occurrence of water mildew.
Three. Treatment of mildew
1, salt 250 grams and 250 grams of baking soda mixed liquid spill on the 100 cm x55 cm x45 cm in the aquarium, insisted several times, significant effect.
In 2, 100 kilograms of water dissolved malachite green 0.3 grams or methylene blue, pickled fish for 10~20 minutes, the number of days after the hyphae fall off. 1, 2%-3% saline immersion, once a day, every 5-10 minutes.
Two to 3, specific millionth (1-2ppm) of malachite green solution immersion 20-30 minutes every day.
4, two parts per million (2ppm) Potassium Permanganate plus 1% ns after the sick fish soak 20-30 minutes.
5, increase the water temperature to inhibit the growth of water mold. A 15 watt UV lamp can be used for several hours a day to effectively suppress and eliminate water molds.
For the weather in Guangdong, may day is a watershed. After May Day, the temperature rises and there is a feeling of going into the summer.
Of course, there are many ways to cool the fish tank in summer, so you can look at several ways:
1. you don't place the mug, display positive sunshine, do not want to say to steal a little natural light to enhance the light, it is best to put in space without the sun shines. In addition, the intensity of the light is also the main cause of temperature rise
2. the room is as airy as possible so that the room temperature itself is not too high and the ventilation is good and that moisture is not too high to corrode the furniture.
3. submerged motor in the tank (mainly oxygen, can refer to "how to aquarium oxygen") is absolutely not too much, appropriate water filtration calculation required, and use the appropriate motor, or in case of excessive temperature stop pumping some auxiliary motor.
4. if you use will be placed in the filter cylinder outside the bar, do not put in the mug underneath the cabinet, because it is not the same with Shen water motor, it is not part of the whole motor are immersed in water, so it can emit heat, if you put it in the closet there will be a the cylindrical filter and warmth surrounded by heightening the temperature of the water in the barrel.
