Why is there always a layer of white foam floating on the fish tank?

It is usually caused by too much organic matter in the water, especially the high content of protein foam. This is a sign that the water is starting to deteriorate, and the water in the fish tank should be adjusted in two or three times 2 3 or all the water should be changed (such as adding cleaning the tank wall, etc., it can be called "cleaning the tank").

There are several reasons why there is foam in the water:

1. The density of the fish is large, the amount of bait is large, and the scale glue on the fish body is also shed, and the excretion is caused by more after feeding. The bubble is smaller.

2. Feed fishmeal bait products, because the bait is scattered and pollutes the water quality or the bait is overused, such as gelatin.

Carboxymethyl. Caused by the increase in the viscosity of water due to coagulants such as cellulose; It may also spoil because the pelleted feed is not eaten by the fish.

Causing water pollution. The foam is large, with a few large bubbles.

3. Oily food causes water surface tension.

Large, poor permeability.

4. If you do not pay attention during the breeding period, some of the eggs discharged by the broodstock will be eaten by the fish, and the other part will be left in the corner or flow in.

In the filter tank, it will become moldy and rotten after a long time.

Day-to-day management matters:

1. Enhance water filtration and clean the filter cotton regularly.

2. Replace those inferior baits that are easy to scatter or have more foam after bait.

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

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

5. Feed frozen water fleas.

or red blood bugs, temporarily turn off the filter for 15 minutes to avoid spoilage in the filter tank.

Before the fish is about to ovulate, the male fish will spit out white foam as nutrients for laying eggs in the future, and this is the case with my family!

It is caused by a large amount of organic matter in the water body and insufficient flow. Change the water BA

Bubbles on the surface of the fish tank? Find out the cause and then solve it.

If you don't have oxygen, it's time to change the water or install an oxygenator.

There is foam on the water surface of the fish tank, and the water and filter cotton need to be changed in time.

If there is foam on the water surface of the fish tank, the water quality is not good, and the water needs to be changed in time to improve the water environment, and at the same time, the filtration should be strengthened, and the filter cotton should be cleaned or replaced so that it can operate normally. It is necessary to reduce feeding in normal times to avoid further eutrophication of the water body, which can lead to microbial blooms. In addition, during the breeding period, if the female fish spawns, it is better to fish it out in time to prevent it from rotting in the water.

Causes of foam on the surface of the fish tankFoam on the surface of the fish tank indicates that the water is too fertile, either because of the high feeding density, or because there is too much feeding, or there are dead fish in the tank. If it is caused by too much stocking density, it is necessary to change to a larger fish tank, or separate breeding. If it is caused by too much feeding, it is necessary to control the amount of feeding to ensure that the fish finish within 5-10 minutes.

If it is caused by dead fish, it needs to be fished out and cleaned up in time.

There are several situations in which the water in the fish tank foams

1. Drugs containing gelatin: In some cases, we need to use some drugs in the fish tank, if these drugs contain gums, and if they are not cleaned and changed in time after use, then the fish tank is prone to white foam.

2. Sunken wood and other substances emitted: Some other substances may be placed in the fish tank, such as sunken wood, bottom mud, etc., these substances are used for decoration, and they may also emit some white foam.

3. Mucus emitted from the surface of fish: Sometimes, the fish itself will emit some mucus that looks like white foam. At this time, the pH of the water may not be suitable, or the fish may be sick, and it is necessary to find a specific cause.

How to solve the problem of white foam in the fish tank

1. Clean up in time after using drugs: After using drugs in the fish tank, you must change the water in time, otherwise it will not only produce some white foam, but also cause a certain degree of harm to the fish themselves.

2. Change the water many times: If it is a decorative object such as sunken wood or bottom mud that emits white foam, then don't worry too much, it will be fine after multiple water changes.

3. Adjust water quality or disease: If the water quality is not suitable, the fish body is easy to emit mucus, which can be adjusted according to the specific requirements of the fish for water quality. Fish can also emit mucus when they are sick, so they need to be given in time**.

If there is white foam on the water surface of the fish tank, the water should be changed once every 3 to 5 days.

The causes of white foam on the water in the goldfish bowl are: too much feeding, no water change for a long time, small or no filtration system, resulting in no organic matter.

method of decomposition, nitrification system can not be established, solution: 3-5 days to change the water, the amount of water change is about 1/4 of the total amount of water is more appropriate.

The water change time should be combined with the weather conditions, it is best to change the water when the weather is fine, at this time the temperature of the air is relatively stable, the fish can adapt, do not change the water for the goldfish at noon under the scorching sun.

The number of water changes varies depending on the season, summer is three or four days to change, spring and autumn is once a week, winter is half a month, plan the time and number of water changes to prepare water in advance, just connected tap water, to dry for 24 hours before use. If well water is used, it should also be dried 24 hours in advance.

Goldfish is one of the world's three famous ornamental fish, originated in China, and has a history of more than 1,700 years.

Goldfish occupies a very important position in China's ornamental fish exports. Goldfish has a beautiful body and a wide variety of species, its body color is red, yellow, blue, purple, black, white, two-color, three-color, five-flower, etc., its body shape has lion head, high head, blister, dragon eye, pom-pom, pearl scales, butterfly tail, tiger head and so on.

The five representative varieties of goldfish are grass gold, red dragon eye, crane top red, blister, and black longevity.

There is foam on the surface of the fish tank, and the simple way is to filter it out with gauze.

Radical workaround:

1. Sedimentation method: leave the water for a period of time, wait until the precipitation becomes clear, and then extract the dirt on it for use.

2. Filtration method: Lack of finch is filtered with fine sand or filter cloth before use.

3. Chemical treatment method: mash the alum and sprinkle it evenly into the water at a ratio of 0·01%. It can make the float settle quickly, and the water becomes particularly fresh after one day. When using alum, the dosage must be mastered, and too much dosage is harmful to fish.

There is white foam on the surface of the fish tank because of the early rest:

The white foam of the fish tank water may be because there are too many impurities in the water, for example, it may be that some drugs used by people have been recently put into the fish tank, and there is a large amount of starch in it, so a large amount of foam is formed on the surface of the water body, and it will not dissipate for a long time.

In addition, if an excess of salt is suddenly added to the fish tank, foam will form on the surface of the water when the filter is opened, and too much impurities or too much salt may occur in the salt. Finally, if the fish tank has recently been filled with new fish, it may be that the new fish themselves are sick, which affects the overall water quality, so there is foam.
