How to raise water for goldfish and open the tank

How to raise goldfish? The key to keeping goldfish is not fish, but water. If you want to raise goldfish well, you must first learn to raise water. The time to change water is usually around dinner, and the temperature of fresh water should be equivalent to that of fish tank water. Let's take a look at how to raise water for goldfish.

How to raise goldfish, raise water and open the tank 1 first, wash and disinfect the tank: the first thing to buy a tank is to wash it. After washing, you can soak in potassium permanganate or sea salt for a while. Potassium permanganate should not be too strong, and then clean the fish tank. Of course, if you put decorations such as stones, you'd better soak them. Rinse with clean water after soaking.

Second, add water: directly add tap water, and let the water stand for a few days in advance if possible. If tap water is directly added, the filter should always be on after adding water, and the heating rod for raising tropical fish should also be on and left for a day or two.

3. Adding nitrifying bacteria: after filtering for one or two days, put the nitrifying bacteria into the fish tank. If it is a good nitrifying bacteria, it is necessary to mix the water in the fish tank and add a few pieces of shrimp or fish food to keep the water circulating.

Huiqingshui

If the green water in the original tank suddenly turns into clear water and there are many green algae at the bottom of the tank, this kind of water is called clear water. This is because there are too many fish and insects in the fish tank that feed on green algae.

Or because of the deterioration of water quality and fish diseases, or because of the lack of nutrition of green algae, a large number of green algae died, leading to the return of old green water to clear water, causing the death of algae and aerobic bacteria, making the water extremely clear and oxygen-free, and becoming stagnant water containing a large number of anaerobic harmful bacteria.

This kind of water can easily make fish sick, so it should be replaced immediately.

How to raise goldfish 2 The key to raising goldfish is not fish, but water. "Raising fish" is actually "raising water". When the water is well raised, fish farming is half the battle. If the water for fish farming is done well, it should be clear and transparent, crystal clear, moist like crystal, and it is living water. Only readers who have really raised water will have a deep understanding. Although this kind of water is fresh water, it feels different from the raw water directly discharged from the faucet.

Let's talk about "water conservation". Goldfish are raised in clean water. With the breathing and metabolism of goldfish, waste is constantly discharged into the water, so the water quality begins to deteriorate. It is necessary to keep the water fresh and clean by raising water, so that the raised water can be suitable for the growth of goldfish for a long time. The traditional method of keeping goldfish by drying, mixing and changing water is a boring and hard work, which makes it difficult for goldfish lovers to persist for a long time.

The modern way of raising water is to rely on the electrically driven filtration system to biologically purify the water and maintain the water quality, which can save a lot of manpower, thus making raising goldfish a relaxed and happy thing. Here are two ways to raise water, which are described in detail.

How to raise water in ancient times

The traditional water-raising method-"mixed water exchange": its purpose is to remove the dirt in the water, including the feces of residual bait, to maintain good water quality, adjust the water temperature and increase dissolved oxygen, thus stimulating the rapid growth and development of goldfish. At the beginning of water exchange, fresh water should be dried by the above method before water exchange. There are two specific methods:

Partial water change:

Concentrate goldfish on one end of a fish tank or cement pool with a folding fishing net, or fish them to other places with a fishing net, and then suck off excess feces, residual bait and other dirt in the pool with a straw. The water absorption depends on the water quality, and generally does not exceed 1/3. It is best to inject the same amount of fresh water along the wall of the pond. This method is often used when goldfish are young, especially when goldfish are found to be abnormal in the afternoon, and this method is used for first aid.

Completely change water:

Completely changing water is often used when the water quality is seriously deteriorated or the moss in the pond is too long, and it is often carried out at the same time as picking fish and dividing the pond. It can completely remove the harmful substances in the goldfish pond. If there is a free pool, you can inject fresh water into the pool for drying 3-5 days in advance, so that when changing water, the water temperature of the two pools is similar, but the water quality of the new pool is clean and rich in dissolved oxygen. All the goldfish in the old pond are fished out, sorted and selected, moved into the new pond, and then the old water in the old pond is drained, scrubbed and injected with fresh water, and a new pond can be formed in a few days, so it can be recycled.

If there is no free pool, it is necessary to catch goldfish in a large basin or put the cage in an adjacent pond for temporary cultivation, put an aerator in the basin and aerate with an air pump. Then, put the old water out of the original pool water, scrub it clean, put in the same amount of isothermal new water, and then fish the goldfish back into the pool.

How to raise goldfish? 3. tender green or brown green old water, clear water and green moss are good water.

If it is the early stage of opening the tank, the goldfish first enters the tank with fresh water and stops eating within one week after entering the tank. 2-3 days after the goldfish enters the tank, the water in the fish tank will become white and foggy. Don't worry about this, because all kinds of colonies began to multiply. If there is no filtration, siphon the bottom with a pipe every day, pump out about 1/5 of old water together with pollutants such as fish manure, and then slowly inject the same amount of new water along the cylinder wall. A week later, a small amount of feeding was started, and the water was changed to 1/5 every day. If there is filtration, the frequency of water change can be controlled at about 3 days.

Try not to change a lot of water frequently at the beginning of cylinder opening.

Two weeks after opening the tank, with the gradual establishment of nitrification system, the water in the fish tank will gradually become clear, and the bottom of the fish tank will slowly start to grow green moss or brown moss (brown moss is also a manifestation of good water quality). The fish tank water becomes green or yellow-green old water or green (brown) moss clear water. At this time, the water quality looks bright and transparent, and basically begins to be in a stable state. In the meantime, just change the water normally (isothermal fresh water).

If it is not filtered, change 1/5 fresh water every 1-2 days, 1/2 every week, 4/5 or completely every 2-3 weeks; If there is filtration, change 1/4 fresh water every 3-5 days, 1/2 every month, and completely change water every 2-3 months.

The time to change water is usually around dinner, and the temperature of fresh water should be equivalent to that of fish tank water. The temperature of fresh water in spring, summer and autumn can be slightly lower than 0. 5 degrees-1 degree, and the temperature of fresh water in winter can be slightly higher than 0. 5- 1 degree. The water exchange rate should be flexibly controlled according to the actual situation. If the pellet bait is fed too much, or it rains, it is necessary to increase the water exchange amount appropriately to prevent the goldfish from lacking oxygen;

If the goldfish raises fresh Daphnia, or the amount of granular bait is small, or the weather is mild and sunny, and the goldfish does not lack oxygen or float, the water change can be appropriately reduced. In winter, the amount of water exchanged should be reduced appropriately. When the water temperature drops below 6 degrees, goldfish will go into hibernation. At this time, they can stop eating and change water.

According to the actual situation, appropriately increase or decrease the amount of water exchange.

If there is an unexpected situation, such as the backflow of clear water, or the rear-end collision of male and female fish in the breeding season, which leads to the female fish laying eggs in the tank, or infectious fish diseases such as parasites, it is necessary to change the water in large quantities or even completely. If it is too late to dry enough fresh water, you can use Yulebao to remove chlorine and use hot water to adjust the temperature.

You can use Youlebao to remove chlorine when you suddenly change a lot of water.

In short, if you want to raise goldfish well, you must first learn to raise water. The water quality will be different in different regions, seasons and goldfish. Only by practicing more and paying more attention can we sum up the methods of keeping goldfish and water that suit us.
