Why do aquatic plants in a goldfish tank bubble?

Oxygen released by photosynthesis.

1.Why do aquatic plants bubble?

Photosynthesis produces oxygen, and that oxygen is what you call a bubble!

Aquatic plants need to be bubbling for photosynthesis and need to cooperate:

1.Light quality and brightness of lighting: The function of the lamp is correct when it carries the "plant cultivation lamp" and indicates the effective band value and power value. The visual brightness of the light perceived by the naked eye has nothing to do with the brightness of the synthetic band of plant light.

Water quality: the hardness is about 2 ° kh, the planting temperature of aquatic plants should not be too high, it is more suitable within 21 to 25 °C, the water temperature is too high, and the respiration rate of aquatic plants will exceed the photosynthetic rate and affect the activity rate of enzymes; The respiration of aquatic plants consumes energy, while the activity of enzymes produces energy, so the energy consumed is greater than the energy produced, and photosynthesis is reduced. The lower the water temperature, the easier it is for carbon dioxide to dissolve and stay in water, and the higher the water temperature, the shorter the time for carbon dioxide to stay in water, and the easier it is to volatilize.

2.Nutrient supply The nutrient supply is based on the base fertilizer and top dressing absorbed by the roots, and the liquid fertilizer absorbed by the leaves, and when the nutrients are insufficient, it will cause poor growth.

3.Addition of carbon dioxide: CO2 concentration in water is preferably 5 15mg L (adjust the concentration according to the aquatic weeds.

The nutrients are supplied with basal fertilizer that is absorbed by the roots.

It is the oxygen released by photosynthesis.

Photosynthesis is reduced.

Aquatic plants carry out photosynthesis in the sun, and oxygen is discharged from the stomata of aquatic plants, because aquatic plants are in water, and the oxygen is discharged through the water, which becomes bubbles.

When the aquatic plants in the fish tank have enough sunlight, they will emit a lot of small bubbles, which is the result of photosynthesis. Any plant has to photosynthesize. Chlorophyll in leaves is an important substance for plants to carry out photosynthesis without chlorophyll.

Plants don't grow properly. In sunlight, the chloroplasts of aquatic plants use the sun's light energy to convert the absorbed carbon dioxide into oxygen, which is then excreted. The blisters we see are oxygen bubbles.

Generally, the roots of plants will rot if they are soaked in water for a long time, but aquatic plants belong to angiosperms, and this plant is not afraid of water. They have many cavities in their stems and leaves, and there is air in them, from which aquatic plants can get oxygen and breathe.

In addition, the cells on the surface of the stem and leaves absorb water. Because it does not have to worry about running out of water to "drink", it does not need the mechanical and conductive tissues that land plants have to support the stems, so its plant body is soft and has no roots.

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

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.

In the process of raising fish, what happens to the bubbles in the fish tank, in fact, this situation is more common when the tank is newly opened, because the new water will emit a certain amount of chlorine, and bubbles will form when it encounters the tank wall.

However, it is also possible that in the process of oxygenation, due to the flow of water, a lot of scattered small bubbles will be formed, which is more common when using a two-in-one or three-in-one all-submersible oxygen pump.

If there are too many aquatic plants in the fish tank, then in the case of temperature life or photosynthesis, the oxygen in the fish tank will be greatly increased, and it is easy to produce bubbles, and there will be bubbles in the fish tank.
