The most important thing to raise ornamental fish is the water used for ornamental fish. The quality of water directly leads to the survival probability of ornamental fish. Therefore, it is very important to ensure the cleanliness of water quality when raising ornamental fish. So what should we pay attention to in the use of water for ornamental fish?

1. What are raw water, fresh water, old water, old water and reclaimed water?

1. Raw water refers to tap water or well water that has just been released without exposure. The water temperature is usually quite different from that of fish ponds (tanks), especially tap water contains more chlorine, which is very harmful to ornamental fish. After use, it will be slightly poisoned, resulting in crooked head, bent spine, cold, congestion at the end of fin, etc. If it is serious, it will soon die of poisoning.

2. Fresh water (submerged water) is tap water, well water or spring water, which is exposed to the sun for 2-3 days, and the water temperature is similar to that of fish ponds (tanks).

3. Old water is dirty water with feces and dirt at the bottom of fish ponds (tanks), including long-term use of aquaculture water.

4. Old water is the general name of clean green, green, old green or greenish brown water in fish ponds (tanks). Among them, light green water is the best There are many green algae floating in the old water, which is a good auxiliary bait for ornamental fish. This kind of water has less organic matter and more dissolved oxygen, and it is often used to raise fish with tender green and clean old water. In addition, there is a kind of water covered with moss and clarified for a long time, which also belongs to the category of old water. If ornamental fish have adapted to this kind of water since childhood, the bait can be treated as ordinary old water; If the ornamental fish is not suitable, it is necessary to reduce the feeding.

5, back to clear water If you find that the original old green water suddenly turned into clear water, a lot of green algae precipitated at the bottom of the pool, this is called back to clear water (commonly known as biting clear water). This is because the redundant red worms in the pond (tank) feed on green algae, or because of the deterioration of water quality and the use of drugs by ornamental fish, or because of the lack of nutrition of water-thin green algae, which leads to a large number of green algae precipitation and death. This kind of water is easy to cause fish diseases and must be replaced thoroughly in time.

Second, how to keep the water clear

In fact, there is a saying that has been handed down, water is clear and there is no fish. This sentence is very reasonable. We often see that the water in the fish tank of a fish friend's house or our own house is very clear. Just like there is no water in the tank, the fish are hanging in the air, which is really beautiful. In fact, this is only a superficial phenomenon, because the water is full of a large number of beneficial bacteria, which are serving you and the water. How to cultivate and maintain these bacteria has become the key to unclear water.

Just being jealous is not the solution, but how you achieve it is the most important thing.

For the cultivation of water, first of all, the filtration system should be sufficient. Many articles say that the water capacity of the filter material is at least %3-%5, but this can only meet the growth of digestive bacteria and meet the minimum requirements. I think at least% 10 of the tank capacity can meet the basic requirements of many fish friends for clean water, and the density of fish should be small, and less feed should be put in. It is best to reach more than %30 of water capacity, and not only physical filtration should keep up, but also biochemical filtration should be improved. Digestive bacteria belong to aerobic bacteria. In order to maintain the growth of nitrifying bacteria, a good environment is needed. It is best to install air strips in the place where the glass ring is prevented, and provide oxygen for 24 hours.

Third, how can fish at the bottom of the tank reach 7X24 hours without residue?

Equipment is a very important link, and there should be a pump with reasonable power. I think it's not as big as small in this respect. Many friends have asked, do you think 15W or 20W is suitable for my pump? In fact, the difference of 5W is very small in terms of power consumption and cost, but the effect can be improved to a higher level.

Not only should the equipment keep up, but also good airflow generation in the cylinder is essential. No matter how good the equipment is, it will not be used, which is basically equal to white blindness. To make the water circulate in the cylinder, the water from the water outlet to the water inlet should be alive and moving. The water flowing out of the water outlet naturally drives the fish to the suction port and is pumped up by the water pump when it is close to the suction port. This is a reasonable process. If the water flow at the outlet is not enough, consider adding a small pump at the position opposite to the suction port to achieve the circulation effect by using the blowing force of external force.

When the flow in your tank reaches a reasonable standard, hey, the fish is gone ~

Fourth, how to arrange the water change cycle reasonably?

The cycle of changing water is related to the species of fish you raise. Some fish like new water, while others like old water.

Fresh water will cause a little discomfort to fish more or less. If the general household filtration system is sound and the flow rate in the cylinder is reasonable, the water change cycle can be kept at one-third to one-fourth of the weekly water change. Every time you change water, you should slow down the speed of water entering the tank, so that the new water can slowly blend into the old water to avoid giving the fish too much stimulation and affecting the state. If there is feces or feed residue at the bottom of the tank, suck it up with a straw. But if there is a reasonable in-cylinder flow, it is estimated that a straw is not needed.

Verb (abbreviation for verb) Daily maintenance of water.

The maintenance of water is simple. Clean the filter materials regularly. The number of filter materials cleaned each time should not exceed %30 of the total filter materials. I don't need to clean them frequently. I only clean it once every 3-4 months, and sometimes I just change it. In addition, the cylinder brush is necessary, because nitrifying bacteria will leave a film in the cylinder, and wiping these off is also very helpful for closing. It is also helpful to add an appropriate amount of nitrifying bacteria after each water change. If you can install a UV lamp and use it for 10 hour every week, you can avoid green algae and the harmful bacteria in the water will be completely killed. Don't directly irradiate the filter material and fish with UV lamp, otherwise it will be all over, because UV lamp is a double-edged sword, and directly irradiating the filter material will kill nitrifying bacteria. If you irradiate the fish ... you are ready to catch the dead fish!

In the process of raising ornamental fish, water quality is of course important, and it is also essential for the cleaning of aquarium. Also pay attention to the density of raising ornamental fish. Don't blindly polyculture, and don't keep too many fish in an aquarium, which is not good for the health of ornamental fish.
