What s going on with the water in the fish tank, what s going on with the many bubbles on the fish t

What's the deal with a fish tank with foam? Is it right to keep a fish in one liter of water? It turns out that this is all a matter of experience.

There are a lot of bubbles on the fish tank for the following reasons:

1. Excess protein in water: If you feed too much when feeding fish, it may lead to excess protein in the water. In this case, the fish tank is prone to foaming.

2. Too many impurities: In the case of no water change for a long time, there will be more impurities in the water. For example, fish feces, fish urine, etc., will cause the viscosity of the water to increase, which can easily lead to foaming in the water. If it is severe, it can endanger the health of the fish and even lead to their death.

3. Too long light time: In this case, the algae plants in the water will multiply, and these algae plants will produce some foam when they breathe. This condition is more harmful because it may cause algae to occupy a large amount of oxygen, resulting in hypoxia in fish.

The solution needs to be determined based on the above three reasons:

1. Control the amount of feeding: Generally speaking, it is better to let the fish be in a state of seven or eight minutes full each feeding, and a large amount of food can not be fed. In the case of a large amount of food residue in the fish tank, it is best to clean it out in time.

2. Change the water regularly: When raising fish, you must pay attention to changing the water, especially when there is no powerful filtration system in the water. Generally speaking, it is necessary to change the water at least once a week or so to ensure that the water quality is clean.

1. There are bubbles on the fish tank, and it is very common in small fish tanks without a filtration system, and ornamental fish will swim to the upper part of the water to breathe oxygen, so it will cause more bubbles on the water surface.

2. Water filtration can be enhanced, the filter cotton can be cleaned regularly, and the inferior bait that is easy to disperse or has more foam after feeding can be replaced.

3. Always check whether there are any fish eating the leftover bait, and remove it in time.

4. Replace part of the new water regularly to maintain the freshness of the water body.

5. Temporarily turn off the filter for 15 minutes when feeding frozen Daphnia or red blood insects to avoid spoilage caused by flowing into the filter tank.

6. If the foam is more serious, it should be divided.

Two or three times to adjust the water of the fish tank 2 3 or change all the water, such as adding cleaning the tank wall, etc., it can be called "cleaning the tank".

The possible scenarios are as follows:

1. Lack of oxygen in fish, this phenomenon is more common in small fish tanks without filtration systems, and fish are floating on the water surface to breathe and swallow air, so it will cause too many bubbles on the water surface, especially cold-water fish such as goldfish and koi.

2. The density of the fish is large, the amount of bait is large, the scale glue on the fish body falls off more, and the excretion is more after foraging, and the foam is relatively small.

3. For some small fish tanks without filtration devices and only aeration devices, it is also possible that there are too many bubbles on the water surface due to the excessive amount of oxygen, but if the water quality is good, the bubbles should disappear soon.

4. The water in the fish tank is too fat, and the organic matter content is too high, including the oil of the feed, the feces of the fish, and the oily substances brought into the fish tank during the usual operation, etc., resulting in the formation of an oil film on the water surface, and then it will lead to more and more bubbles on the water surface, which cannot be dispersed for a long time.

1. Check whether there is rotten material in the water;

2. Check whether the filter cotton should be cleaned or replaced;

3. Check if any fish have died;

Solution: 1. Turn off the filtration system;

2. Replace the water in the tank, one-fifth to one-third;

3. After changing the water, don't be in a hurry to open the filtration system, clean the filtration system, especially the filter cotton. It is best to replace the filter cotton;

4. Before opening the filtration system, add twice as much nitrifying bacteria as usual;

5. Open the filtration system and burst oxygen;

6. Add salt, iodized salt is not enough, it has to be sea salt, 0.3% of the water body.

The presence of bubbles in the fish tank may be due to the fact that the water in the newly opened tank emits chlorine gas, forming small bubbles. When using a 2-in-1 or 3-in-1 all-latent oxygen pump to inject oxygen, many small bubbles will also form. However, if there are more aquatic plants in the tank, the temperature rises or photosynthesis will also cause an increase in oxygen and many bubbles will appear.

The temperature is too high: When the temperature in the fish tank is too high, a lot of bubbles will appear. These bubbles will stick to the equipment inside the fish tank or to the walls of the fish tank.

Chlorine: When the tank is opened, if the chlorine in the water is not completely volatilized and enters the fish tank, there will be a lot of small bubbles.

Sufficient oxygen: The bubbles in the fish tank may also be caused by too much oxygenation, but as long as the water quality is good, these bubbles will disappear quickly.

1. Control the water temperature: If the water temperature of the fruit is too high, the keeper needs to cool down appropriately, so as to ensure the comfort of the living environment of the fish, but also reduce the appearance of bubbles. In summer, you can choose to use a fan to cool down the fish tank.

2. Trapped water: Before filling the fish tank, you need to trap the water first, so that there will be no bubbles in the fish tank after the water is filled. Tap water can be exposed to the sun, or you can choose to use an oxygen pump to continuously oxygenate for 2 hours, which can also eliminate chlorine in the water.

3. Proper oxygenation: If the demand for oxygen is not very high, the keeper can properly oxygenate for a few hours a day to ensure that the oxygen is sufficient.

There are many bubbles on the water surface of the fish tank, which may be caused by the water in the fish tank being too fat, the high organic matter content, or the isolation box is close to the upper tank wall of the fish tank, and the water cavity fiber flow cannot flow normally. It is also possible that the amount of oxygen in the fish tank is large, and a large number of bubbles will appear on the surface of the water.

In the process of raising fish, many people should have encountered a lot of small bubbles on the water surface of the fish tank. In fact, this may be because the water in the fish tank is too fatty and the organic matter content is high, so there will be many small bubbles in the process of organic matter decomposition.

Or because the isolation box in the fish tank is close to the upper wall of the fish tank, then the water flow will not flow normally, and a lot of bubbles will be formed, and they will eventually float on the water surface.

There is no filter device in the fish tank, only when the oxygen is decorated, the amount of oxygen in the tank will be larger, so it will also cause a large number of bubbles to appear on the water surface, but in the case of better water quality than sails, this bubble will generally disappear quickly.

The foam in the fish tank water is related to the density of the fish, and the density of the fish is large, and the excrement will cause the water quality to deteriorate, which will lead to the production of some foam. There are dead fish in the tank, and they have begun to spoil and foam will appear in the water. Foam in the tank water is also associated with fishmeal bait, which can contaminate the water quality and cause foam to appear on the water.

The water in the fish tank has foam, which may be the density of the fish, the scale gum on the fish body falls off, or it may be caused by excessive excretion after feeding every day.

There are dead fish in the tank, and they have begun to rot badly and stink, and the water emits a corrosive smell, and this bubble is relatively large. It is recommended to fish out the dead fish and change the water in the fish tank in time so as not to affect the survival of other fish.

Foam in the tank is also associated with fishmeal bait, which contains a high content of coagulants, which can pollute the water quality and cause foam if they are not eaten in the water for a long time.
