What s going on with the fish tank with a lot of foam on it?

There is a lot of foam on the water in the fish tank, because the water in the fish tank is dirty, and the excrement of the bait or the food fed will not be eaten in time will lead to the deterioration of the water quality, and it will be fermented, so there will be a lot of foam.

1. Excessive feeding causes excessive protein in water.

2. If the water has not been changed for a long time, fish feces and fish urine make the water quality thicker.

3. Relying too close to the light source, the water body is eutrophicated, which leads to the growth of algae.

Solution: 1. Reduce the amount of feeding and change the water appropriately.

2. It is recommended to change the water, about 40%, and the fish will not be able to stand it and will die easily.

3. The bubbles on the water surface are caused by the respiration of algae on the water surface, which needs to be removed, otherwise it will lead to a lack of oxygen in the fish.

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.

It is to use the method of increasing nutrients to cause bubbles.

How to solve the problem of foam on the water surface of the fish tank? Usually if we look at it for a few days, we can see that these bubbles disappear quickly. Of course, if these bubbles are too much of an aesthetic, we can also alleviate this by changing the water properly.

However, this proper water change is not conducive to the stability of water quality. Because the water has been changed, the water quality of the fish tank has also fluctuated. Therefore, the most recommended thing is that everyone can also leave him alone and let it go for a few days.

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 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".

Change the water in time, the water in the fish tank has foam, which means that the water quality is not good. Strengthen filtration, reduce feeding, and remove eggs.

1. Add water to the fish tank, whether it is well water or tap 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 pipe, 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, filtration, 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, the nitrification filtration system has not yet been established, and the addition of nitrifying bacteria to the water 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, if it is only for this reason, we can fish out the foam, and after a period of time, the nitrification system will be established to play a filtering role, and the situation will be improved.

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.

If there is a sudden change, the weather may become cold, and the biochemical abnormalities will produce foam, pay attention to strengthen and gradually change the water and stop eating.

Here are some solutions to this problem:

1.Tap water contains a small amount of impurities in organic matter, after a period of time in the water tank, the organic matter of the oil dissolves in the water and surfaces.

2.Eight of the algae's tissues become "oleotic". When the algae die and decay, the oil dissolves in the water and then surfaces. When new water is injected, the grease attached to the aquatic weeds and tank walls is washed out, and then it rises to the surface, resulting in a water surface oil film.

3.Grease produced by microbial remains or old waste, bait, organic matter, etc. The oil film is most severe when there is no flow on the water surface.

4.The filter media in the filter is too dirty, and grease is spilled.

Effect of water surface grease:

1.Hinder the escape of exhaust gas or water temperature in the water, make the water quality deteriorate prematurely, and increase the number of water changes.

2..Hinder the light source from entering the water and affect the photosynthesis of aquatic plants.

Solution:1The oil film processor is used to make the oil film enter the filter, and the filter cotton in the filter material is used to adsorb, and the oil is decomposed by nitrifying bacteria.

2.Slowly collect the oil film in a cup and discard it.

3.Blotting paper can be placed at the opposite corner of the outlet (oil film assembly area) to absorb the oil film.

4.The horn bucket mixer is installed, the oil film is sucked into the mixer, injected into the water and mixed with the water, and the filter cotton is adsorbed and decomposed through the filter.

5.Remove dirt from the filter.

6.Keeping oil-fed fish (fish that float on the surface of the water to eat dirt), such as black girls or black teapots, can reduce the formation of oil films.

7.The most recommended and only way to treat both the symptoms and the root causes is to establish a stable biochemical system.

First, check the water for decaying material.

Second, check whether the filter should be cleaned or replaced.

Third, to see if there are any fish that are already hanging.

Workaround:1Turn off the filtration system.

2.Replace the water in the tank, one-fifth to one-third (preferably one-third) 3After changing the water, do not rush to open the filtration system, and 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 enough, it has to be sea salt, water body.

Summary. 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.

What's the deal with foam on the top of the water in a fish tank?

Hello This is a very good question, I need a little time to answer, please be patient.

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.
