If the pH value of water quality changes too much, what will be the effect on koi?

About the effect of water quality pH on fish.

Koi fish requirements for water quality is not very high, is a simple breeding of large ornamental fish, there are many species, in general, the fish tank is often changed water, because fish in poor waters are easy to get sick, thus affecting the ornamentation. Koi fish are raised in ponds, but they take up too much space, so many people keep koi in fish tanks. However, the water quality of koi fish raised in a fish tank can easily deteriorate, and if the water is not changed frequently, it will affect the growth of koi fish.

Therefore, if you want to raise koi well, you must purify the water quality of the fish tank, because water is the most important environment for fish to survive.

1.Maintaining good water quality ensures healthy growth of koi fish, a fish that requires a lot of food and activity. They excrete a lot of food scraps every day, as well as a lot of feces.

These organic matter are a breeding ground for bacteria, allowing them to multiply and also make koi fish sick and die. The traditional method of purifying water quality in fish ponds is complex and troublesome to implement, especially if the filtration is not timely in the later stage, which may further lead to fish diseases. Therefore, we need to change the water and disinfect it frequently.

2.We can install a fish pond water quality filtration system, which is more advanced than the previous multi-stage filtration, only one water pump, one fish pond filter and pipeline can form a complete filtration system, and the cost is low, the floor space is small, the installation is simple, the labor is saved and the later maintenance is convenient, and the filter only needs to be cleaned regularly.

3.Microorganisms and water purification stones can also be added to the pool. These water purification stones are made from sand and stone mixed with porous materials.

They play an important role in purifying the water quality at the bottom of the fish pond. Fish fecal residue can be broken down by allowing microorganisms to decompose the feces in the fish pond in advance. These organic wastes decompose harmful substances, reduce ammonia nitrogen content, and in order to eliminate odors, each stone can purify 3 tons of water, and the service life is 2-3 years.

It can be said that the method of water purification in fish ponds is once and for all, and there is no need to purify the water every day or worry about the deterioration of water quality.

The most important thing for koi fish farming is healthy water quality. The water quality of the fish tank water directly affects the health of the golden fish. The above points are very useful for adjusting the water quality of the fish tank.

Koi do not have very high requirements for water quality, and they do not need to change the water frequently, so they can be guaranteed to change once a month.

The requirements for water quality are very high, this is a freshwater fish, and the water needs to be changed frequently, so that the koi will grow well.

Pour a low-concentration aqueous solution of sodium bicarbonate into the fish tank several times. The pH of the water is checked every time it is released. Stop putting it in when the pH reaches about the same level. If the pH is too high, you can put some sodium dihydrogen carbonate to lower the pH of the water.

There are two main methods of adjusting the pH value of koi: chemical reagent adjustment method and traditional adjustment method

1. Chemical reagent adjustment method: Koi can adjust the pH of the water to about it. After sodium bicarbonate is dissolved in water, it can increase the pH value of water quality and make the water weakly alkaline.

The method of use is to pour a low concentration of aqueous sodium bicarbonate solution into the fish tank in multiple times. Be sure to pour a small amount of aqueous solution and constantly check the pH value of the water. Stop discharging the drug when the requirements are met.

If you overdose, you can change some sodium dihydrogen carbonate to lower the pH of the water.

2. Traditional adjustment method: If you want to increase the pH value, you can put some coral sand in the fish tank. The main components of coral sand are sodium carbonate and sodium hydride, which are not easily soluble in water, but there are trace parts that are soluble in water and can produce OH negative ions, making the water weakly alkaline.

If the pH is too high, you can put in dried leaves or pineapple peels to lower the pH of the water.

There are two main types of pH adjustment method for koi: chemical reagent adjustment method and traditional adjustment method

1. Chemical reagent adjustment method: Koi can adjust the pH of the water to about it. After sodium bicarbonate is dissolved in water, it can increase the pH value of water quality and make the water weakly alkaline.

The key to use is to pour a low-concentration aqueous sodium bicarbonate solution into the fish tank several times. When pouring in the aqueous solution, be sure to put in a small amount, and constantly check the pH value of the water. When the request is reached, the release of medicine is stopped.

If the drug is overdosed, you can change some sodium dihydrogen carbonate to lower the pH of the water.

2. Traditional adjustment method: If you want to increase the pH value, you can put some coral sand in the fish tank. The main components of coral sand are sodium carbonate and sodium hydride, which are not easily soluble in water, but there are trace parts that are soluble in water, and OH negative ions can occur, making the water weakly alkaline.

If the pH is too high, you can add dried leaves or pineapple peels to lower the pH of the water.

2. How to maintain the water quality of koi carp.

The indicators of the water body are not single, but precisely linked. To ensure excellent water quality, the first step is to feed the koi carp. Feeding can be seven minutes full, so that there is no excess food and polluting the water.

Secondly, we should be diligent in changing the water, and choose the trapped water to change the water, and replace one-third of the water in the fish tank every time we change the water.

You go to a chemical store and buy a pack of test strips, and after five minutes of putting a piece of paper in water, take out the sample and determine the pH value. If it is acidic, you can add baking soda to adjust, and if it is alkaline, you can add vinegar to adjust. Until the pH reaches seven neutral!

1.Improve the alkalinity of the water body (ph value): Sodium bicarbonate: also known as baking soda, which is often called a noodle driver, the chemical formula is NaHCO3, which can increase the pH value of water quality after being dissolved in water, and it is weakly alkaline water quality.

2.Reducing the alkalinity of the water (lowering the pH value):

These professional knowledge of fish farming, you must consult professionals, do not ask others on the Internet, some people tell the wrong pH value acid-base balance, then the fish will die.

When raising koi, choose a weak alkaline water with a pH value and keep the water temperature between 20 and 25 degrees. At the same time, when changing the water, it is necessary to keep the water temperature and the water temperature in the tank consistent to avoid a temperature difference greater than 3 degrees. If the pH value of the water quality drops to about the same level, it will make its body color lighter and suffer from gill rot.

Water quality requirements for koi farming.

When raising koi, it is best to choose a weakly alkaline water quality, about the pH value is between the pH value, and the most suitable water temperature for koi is between 20 and 25 degrees Celsius, which can maintain the vitality of koi.

When raising koi, you should pay attention to the water change, try to keep the water temperature and the water temperature in the tank consistent, to avoid the temperature difference and make the koi sick, and the temperature difference of the water change should not be greater than 3 degrees.

Although the requirements for water quality are not particularly high, if the pH value drops to about one, it will cause the color of the koi's body to become dull, and even cause it to suffer from gill rot.

Koi fish are mostly used for ornamental purposes in our daily life, and koi fish are also developed from crucian carp.

Some people say that koi fish can be taken, but in the whole process of our feeding, the concentrate feed of koi fish is only to make them full, and they do not think about whether the concentrate feed has preservatives, and whether people will have *** after eating, so whether koi fish can be taken varies from person to person, koi fish have a lot of nutrients, and the use value is very high.

Koi fish are raised, and the water hardness is slightly lower and the water quality environment is better. But both soft and hard water can raise koi. The total hardness ranges from 100 ppm to 400 ppm.

However, it should be avoided to move koi fish abruptly from soft water to harder water, or from hard water to less hard water. so as not to cause allergic reactions to the fish.

TDS value is the total dissolved solids content, which refers to the total amount of dissolved components in water, including the total amount of various ions, molecules and compounds dissolved in water, which is not a value that needs to be detected by fish farming.

The overall requirements for water quality of koi are as follows:

1. Water temperature: The water temperature range of koi fish is 2-30, and the optimal living water temperature is 20-25. In the water at this temperature, koi fish swim actively, have a strong appetite, have a strong physique, and are brightly colored. However, the water temperature should not change suddenly, and the temperature difference should not exceed 3 when changing the water.

2. Hardness: above.

3. pH (pH value): Koi fish are required to live in slightly alkaline water, and the most suitable pH value is. Koi do not like sudden changes in water quality, so do not suddenly put them from water with a low pH into water with a high pH value, so as not to cause discomfort due to the large difference in pH value.

Koi fish are exposed to weakly acidic water for a long time (pH value), which not only has a bad body color, but also is prone to gill rot.

For koi fish farming, koi can be pH 6 and skin posture between 5 and 5, but if the growth of koi is taken into account, it is necessary to configure water quality conditions suitable for koi survival. Koi fish like to live in slightly alkaline water, and the most suitable koi fish have an alkalinity pH between to .

However, in the process of koi farming, the pH value will be lower and lower, so the water needs to be changed and adjusted during the breeding process. There are many reasons for the pH change in the process of koi farming, such as the aging of some filter media, the long-term non-change of water, and the gradual accumulation of organic matter in the water quality. These organic matter are mainly the accumulation of residual food residue and koi excretion, and the products of koi excrement under the action of self-managed bacteria and heterogeneous bacteria are ammonia and nitrite and other harmful substances, although nitrate has no direct harm to koi.

The increase of ammonia will lead to an increase in the pH value of water quality, and when ammonia is nitrified, it will be converted into another harmful substance, nitrite, and the pH value of water quality will decrease.

The koi fish is a fish that is very adaptable to water temperature, and it can survive normally in water between 5 and 30 degrees Celsius. However, the optimum water temperature is in the range of 20-27 degrees, and too high or too low may affect its growth and development. So, in summer and winter, when the water temperature is extreme, you can adjust it a little so that the water temperature is between 20-27 degrees.

This is more beneficial for their growth and development. <

The koi is a cold-water fish, but it is very adaptable. It is very adaptable to water temperature, between 5-30 degrees, it can survive normally. However, it also has the most suitable water temperature range for its growth, specifically between 20-27 degrees.

Water that is too cold or too hot can also affect its development to a greater or lesser extent.

In the summer, the water temperature may be high, and in the winter, the water temperature may be low in some areas, so it is necessary to adjust it manually. In the summer, it can be cooled by shortening the interval between water changes, etc.; In winter, some equipment such as heating rods can be used to increase the temperature of the water. Although the temperature is not suitable for its life, it will cause its growth and development to slow down, which is not conducive to ornamentation, so it is recommended to adjust the water temperature to the most suitable range.

Overall, the pH is between the levels, and koi fish can basically survive. However, the pH value that is most suitable for the growth and development of koi is around the same level, that is, it is better to be slightly alkaline, and it has the fastest growth and development rate in the environment of weak alkaline water, and it is not easy to get sick. If possible, try not to choose acidic water, so that the water may cause the koi to get sick and slow down the growth and development.

If you use tap water at home, pay attention to drying it before using it.
