How can there be bubbles when the new fish tank is added with water, and what happens when the fish

There are bubbles for the following reasons:

1. Add water to the fish tank, whether it is well water, tap water or sun-dried water, the water temperature just added to the fish tank must be lower than the indoor air temperature, because the temperature is low, the solubility of dissolved oxygen and other gases (chlorine, etc.) in the water will be high, and the indoor temperature is higher than the water temperature, so as the water temperature in the fish tank increases, the solubility of the gas in the water decreases, and the gas will be released from the water, so that bubbles will condense on the surface of the tank wall, filter, and aerator pipes, and stick to it. If the fish is released at this time, it will condense bubbles on the surface of the body or even in the body, which is one of the causes of "bubble disease", and can even cause the death of the fish.

2. If the new filter material, filter stone, etc., is not cleaned, and the new water is inflated with an air pump, many bubbles will also be generated. This bubble generally floats on the surface and is a sticky substance that can be fished out. The solution is to increase the activated carbon to adsorb the viscous substances in the water, and the filter media should also be cleaned again.

3. When the new water is not raised, we may add nitrifying bacteria to the water, which may also produce bubbles, because the culture medium for cultivating nitrifying bacteria may contain more organic matter. When aerating, a layer of bubbles will be produced on the surface of the water that is not easy to break, and if it is for this reason alone, we can fish out the foam, and it will be fine after a while.

4. The last reason is that the cylinder wall is unclean, and the gas in the water releases condensation, but in fact, the water is not in contact with the cylinder wall glass. Just wipe the bubbles off.

Solution: 1. Turn off the filtering system.

2. Replace the water in the tank, one-fifth to one-third (preferably 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 foam.

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

5. Turn on the filtration system and burst oxygen.

6. Add salt (iodized salt is not good, it has to be sea salt, water body.)

The presence of foam on the surface of the water indicates that the water contains a lot of organic matter, especially high protein content. This is a sign that the water is starting to go bad. There are several reasons why there are bubbles in the water:

1. 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.

2. A large number of dead fish or live bait have died (left in a corner or dark place without being found), and have begun to rot and stink severely, and there is already the smell of rotting corpses in the water. These bubbles are relatively large, but they can also come in a variety of sizes.

3. Feeding fishmeal bait products, because the bait is scattered and pollutes the water quality or the feed is overused with gelatin and carboxymethyl cellulose.

and other coagulants to increase the viscosity of water; It is also possible that the feed is too small and not eaten by the fish, resulting in water pollution. This foam is larger and is accompanied by a small amount of large foam.

4. Feed plenty of daphnia.

In particular, large daphnia are caused by the decomposition of some of them after death. This bubble is a small to medium foam.

5. Acute death of water earthworms.

caused (caused by bacteria). The water is extremely turbid, and the foam is generally small, so it is recommended to clean or clean the tank in time.

6. Oily food causes water surface tension.

Large, poor permeability.

7. If you don't pay attention to the breeding period, some of the eggs excreted by the broodstock will be eaten by the fish, but some of them will be left in the corner, or flow into the filter, and they will become moldy and rotten after a long time.

Workaround

Different treatment measures are taken in different situations, but the main method is to improve water quality or strengthen filtration by appropriate water exchange.

Although there is a filtration device that can remove the oil film, and a large fish tank can also solve the problem of the oil film by increasing the water level difference of the filter tank, if the water quality is not good for a long time, it is useless.

Appropriately reduce the stocking density, reduce the number of feeding, try not to feed the food with too much fat, reduce the amount of oxygen with a large amount of oxygen, try not to use some water-insoluble drugs, etc., and improve all aspects one by one, so that we can receive good results.

Any problem that arises in the fish tank is not something that can be easily solved by simply changing one aspect, even if you may have solved a problem at the time, it may be repeated after a while. Any problem that arises in the fish tank, we must go to the comprehensive management.

1. Lack of oxygen in fish.

This phenomenon is more common in small fish tanks without filtration systems, where fish float on the surface of the water to breathe and swallow air, so it can cause too many bubbles on the water surface, especially cold-water fish such as goldfish and koi.

2. The amount of oxygen is too large.

For some small fish tanks without a filter device and only an aeration device, 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 quickly.

3. The organic content is too high.

This is the main problem, that is, the water in the fish tank is too fat, the organic matter content is too high, including the oil of the feed, the feces of the fish, the usual operation of oily substances brought into the fish tank, 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 can not be dispersed for a long time.

Fourth, some drugs.

Some drugs do not dissolve well in water, and their excess residue will float on the water surface, resulting in excessive accumulation of debris on the water surface, and then forming an oil film.

5. There are some other devices in the upper part of the fish tank.

For example, the isolation box for raising guppies is close to the upper wall of the fish tank, which causes the water to not flow normally, and debris and bubbles will accumulate in this location, forming a lot of bubbles.

Bubbles in the fish tank? Whether it is caused by these 4 reasons is also very simple.

Possible causes of small bubbles:

1) Directly changed to tap water, tap water has been treated with bleaching powder, containing hypochlorous acid, easy to volatilize when heated, and directly put into the fish tank to produce bubbles. Hypochlorous acid is not good for organisms, so it is recommended to change the water or use dried water;

2) The water flow of the pump is large, and the outlet pipe has a gap to contact with the air, and the entrained air enters the fish tank to produce bubbles, which is the same as the principle of the three-in-one pump with the function of flushing;

3) Whether there is an air pump in the fish tank, and it is possible that the air pump is close to the water inlet; The reason why the bubbles are not easy to disperse may be that there are too many polymers in the water or there is an oil film on the water surface, which makes the bubble tension change not easy to break.

Bubbles are oxygen that is not dissolved in water.

1. When the water is just changed, the water enters another environment and the temperature changes, causing the solubility of oxygen in the water to decrease, and the bubbles are squeezed on the fish tank wall due to the tension of the water.

2. These bubbles are harmless and will float up on their own after a few hours; Or a slight shock will break away from the cylinder wall, surface and crack.

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.
