How to change the water quality of the fish tank?

Question 1: Experts please answer how to change the water quality in the fish tank. Water is not clean water, but good water. The significance of filtration is to make the water look clean, and to cultivate nitrifying bacteria to make the water suitable for fish. Grow!

Adding salt when changing the water will have negative effects. After all, goldfish are not saltwater fish!

The rotten tail may be a reaction of the fish not adapting to the water in your fish tank. It is recommended to strengthen the filtering material. There is no need to change the filter cotton frequently. Change the water less every time and have a chance to bask in the sun!

Question 2: How to improve the water quality of the fish tank? ! When the temperature is high, a lot of algae will easily breed in the water, causing the water quality to deteriorate. Pay attention to the cleanliness of the fish tank walls and remove algae on the fish tank walls in a timely manner. In addition, do not feed too much to prevent the bait from spoiling and polluting the water quality. It is also a good idea to change the water frequently, or place aquatic plants in the fish tank, which can also help absorb and decompose impurities.

Question 3: How to maintain the water quality in ornamental fish tanks? Nowadays, we can see ornamental fish tanks in many places, and some people also have their own ornamental fish tanks in their homes. They want to make the ornamental fish tanks ornamental. The water quality in the fish tank requires special attention, but many people who have raised fish know that it is difficult to maintain the water quality in the ornamental fish tank. So do we have any skills that can help you? Let us find out together. . In the traditional concept, when we change the water in ornamental fish tanks, we always change the water in small quantities and in batches, because the turbulence in water quality caused by large amounts of water change is often accompanied by symptoms such as lying in the tank, shrunken fins, food refusal, and fading, and water change is the most direct improvement. The water quality method is also the fastest and most direct way to reduce the content of harmful bacteria in the water body. Generally, tap water must be dried and circulated before it can be replaced. Tap water is often circulated in a large sink for at least one day. The residual chlorine in tap water has a corrosive effect on the gills of fish. Drying the water can volatilize the residual chlorine in tap water, meeting the requirements for raising fish. Often we don’t have enough space in our homes to store water containers. How to quickly remove chlorine residue, using water quality stabilizer is the simplest method. So if you don't have the conditions for drying water, the simplest method is to use an appropriate amount of water stabilizer in the replaced tap water. It is very simple to use old water to raise fish in ornamental fish tanks. It is nothing more than extending the water change cycle and reducing the amount of water changes. However, this will cause the fish in the ornamental fish tank to have a low appetite, slow growth rate, serious bacterial growth and easy disease. The field does not use filtration but water change. Water change is their most direct means of adjusting water quality. We can learn from this method and find the correct method through continuous experiments.

Question 4: How to improve the water quality of the fish tank? How to maintain water? Only when the water quality environment in the fish tank is good can the fish be raised for a long time, and the fish can grow beautiful and healthy. Of course, improving the water quality of fish tanks and raising good water is not just a matter of words. In the breeding process, we still need to implement specific things, improve the water quality of the fish tank through actual breeding, and raise a tank of good water and good fish.

The first step to improve the water quality of fish tanks and raise water: Don’t raise fish too intensively. Keep a reasonable number of fish in a limited tank space. (According to the actual size of the fish tank, the density of fish farming should be reasonably controlled.) The second step to improve the water quality of the fish tank and raise water: Feed the fish regularly every day, and pay attention when feeding the food. It is best to do It can not only meet the dietary needs of the fish, but also prevent food residues from remaining in the fish tank and avoid damaging the water quality environment. The third step to improve the water quality of the fish tank and raise water: Install a powerful filtration system in the fish tank. Use this system to remove fish excrement and keep the fish tank clean. The fourth step to improve the water quality of the fish tank and raise water: When feeding the fish, be careful not to put oily food into the fish tank. Because the oil will float on the water and isolate the air, the oxygen in the water will not be replenished, which will not only pollute the water environment, but also cause death from lack of oxygen in the fish tank. PS: There is another most direct way to improve the water quality and environment of the fish tank, and that is to change the water. However, this kind of water raising is not a long-term solution. To raise a tank of good water, you should still consider it from the perspective of feeding. Improving the functions of breeding equipment and scientific breeding are the best ways to improve the water quality of fish tanks and raise good water~~~~~~

Question 5: How to improve the water quality of fish tanks 1. Maintain regular Change the water

2. Take out uneaten feed in time 3. Clean the filter cotton frequently

4. Establish nitrifying bacteria

Question 6: pH of fish tank water (PH) How to adjust? Water is the environment that fish rely on for survival. As the saying goes, "raise fish first and raise water first." The quality of water directly affects the growth and health of fish. Different aquatic organisms have different requirements for water quality conditions. When raising each aquatic creature, the water quality and environment standards must be adjusted according to its standards. For example, different fish adapt to different water pH, so the pH of the fish tank water must be scientifically adjusted to meet the requirements of the fish.

In fact, it is not difficult to adjust the pH of water quality. There are currently some substances on the market that specifically adjust the pH of water quality. You only need to choose the appropriate pH adjustment stone according to the aquarium species you raise. Generally speaking, as long as these pH adjustment stones are placed near the filter tank or water outlet, the pH in the fish tank can be slowly adjusted.

Currently, pH increasing and decreasing agents on the market are mainly divided into two types: powder and liquid. When the dosage is increased, the pH value can be increased, and when the dosage is reduced, the pH value can be effectively lowered. For example, you can choose soda water to adjust the pH of the water. Phosphate soda water can lower the pH value of water.

Question 7: How to keep the fish tank water clear? There are three main ways to do this. Personal experience

1. Add some digestive bacteria, which can be purchased at the flower and bird market

2. Use bamboo charcoal to absorb them.

3. Use an automatic oxygen flushing and water changing machine to clean the filter cotton.

Of course, the best thing is to create a better environment yourself. Don’t overfeed and try to keep the fish active. , it can also reduce pollution. A sunny place can help nitrifying bacteria decompose harmful residual substances.

Question 8: How to judge the quality of the water in the fish tank. If there is fishy smell, fishy smell, or even the smell of ammonia, then there must be something wrong with the water quality. 2. Testing indicators 1. Ammonia and nitrite

Nowadays, when everyone talks about whose water is better, the first thing they think of is whose water is clearer, and the quality of the water is judged by the clarity of the water. In fact, this is a wrong view. Water clarity is important, but it is by no means a decisive indicator for judging the quality of water, because even if the water is not clear, even if the ph and hardness of the water are not ideal, etc., these are all harmful to fish. It is not fatal, but the toxins in the water can directly kill the fish. Why do we spend so much money on configuring the fish tank's filtration system, purchasing filter materials, and cultivating nitrifying bacteria? The main purpose is to remove toxins from the water. "Non-toxic" is the most basic condition for fish farming and good water, but it is also the most critical indicator. Toxin index is the decisive index to determine the quality of water, ranking first. As long as toxin indicators are detected, no matter how clear your water is, it is not good water and is not suitable for fish farming. The presence of toxins means that your nitrification system has not been established and perfected, and the water has not been well maintained. The toxin index of truly good water must be zero. This is a non-negotiable index with veto power.

Determining the toxin indicators of water cannot be seen with the naked eye, and must be detected using a testing solution.

Fish live in water, just like people live in the air. If the air is full of poisonous gases, people will It cannot survive, and the same is true for fish. So what are the toxins in the water, and how are they produced?

Toxins that are fatal to fish include ammonia and nitrite. They are both highly toxic and can cause fish death at very low levels. When the ammonia concentration exceeds 0.012 mg/L, fish are in danger of being poisoned. Nitrite content below 0.1 mg is safe and healthy water quality, 0.1 mg is mild pollution, and above 0.25 mg is serious pollution. At 1 mg or above, aquatic organisms will begin to Towards death.

The production of toxins is like this: organic matter such as fish excrement and residual bait will cause heterotrophic bacteria to multiply in the water, and the metabolite of heterotrophic bacteria is highly toxic ammonia. In a mature nitrification system, ammonia will be immediately decomposed into nitrite by nitrifying bacteria and then decomposed into nitrate by nitrifying bacteria. The toxicity of nitrate is very low and can be reduced by changing the water. This is why we need to change the water in our fish tanks. reason.

2. The structure of the bacterial community

Why do some fish always get sick? In addition to the physical constitution of the fish, another very important point is the structure of the bacterial community in the fish tank. . When pathogenic microorganisms multiply in a fish tank, fish with weak resistance will inevitably become ill. The ideal flora structure should be dominated by probiotics, forming a strong flora in the fish tank to inhibit the growth of pathogenic microorganisms. The number of bacterial colonies can be measured, and the national fishery water quality standards stipulate that the total coliform bacteria should not exceed 5,000 per liter of water. We cannot achieve this indicator in our daily fish farming, but we can achieve the goal by adding EM bacteria. I will introduce how to use EM bacteria tablets for daily water quality maintenance in the next article.

3. PH, hardness

These two indicators generally do not need to be adjusted, and they are not indicators that must be tested. Ph6.5-8.5 is good water for fish farming. Generally, the ph of city tap water is around 7, which is neutral and does not need to be adjusted. If you must use a gentle method to adjust the pH to avoid discomfort to the fish due to excessive pH changes, I will write a special post explaining the pH adjustment method in the future. The hardness of water varies greatly depending on the water quality in different places. Generally speaking, the hardness of water that people can drink is suitable for fish farming. This indicator generally does not need to be adjusted, unless soft water is needed during the breeding period of fish and the hardness must be reduced. The adjustment method is also There are many, which will be discussed specifically later.

4. Dissolved oxygen

The amount of dissolved oxygen in water is an important indicator of water quality. Dissolved oxygen in fish farming water must be greater than 5 mg/l for more than 16 hours out of 24 hours a day, and must not be less than 3 mg/l at any time. Insufficient dissolved oxygen will cause fish to lose appetite, physical fitness, and disease resistance. When the dissolved oxygen in the water drops to about 1 mg/l, the fish will float. This indicator is generally not tested when raising fish at home. When raising a Luohan fish, you only need to ensure that the filter can work normally and the water is flowing, so there will be no lack of oxygen. When there are many fish, oxygen is needed. 5. Temperature

Many people do not take this indicator seriously. In fact, this is wrong. Temperature is a very important indicator for tropical fish...>>

Question 9: If you are raising tropical fish, how can you improve the water quality of the fish tank? The hardware facilities are first of all related to the size of the fish tank, the density of the water and the type of fish.

Then there is the filtration system, if it is a bottom filter or a large DIY one. The upper filter tank can ensure that enough filter cotton and filter materials are placed

Finally, oxygen, filter material quality and nitrifying bacteria
