By the way, why does the water in the fish tank turn green and how to remove it? thank you

The green water in the aquarium is caused by the growth of green algae in the water.

The fish tank should not be exposed to the sun, so it should be thoroughly cleaned regularly.

Through thorough cleaning, its "seeds" will be cut off, green algae will not breed and spread quickly, and the water will not turn green quickly.

Extended data:

Daily maintenance of fish tank water;

Control stable water quality

Stable salinity

Stable pH value

Regular local water change

Check the filtration system regularly.

Matters needing attention in fish tank filtration system:

Be sure to connect the water pipe after cleaning. Note that the water pump can not only filter the water in the tank, but also pump the water out of the aquarium.

Always check whether the water flowing out of the filter is normal and whether there is blockage. In addition, the first layer of biological cotton or filter element that blocks dirt should be cleaned frequently and replaced regularly.

Activated carbon should be replaced regularly.

Clean the dirt in the protein separator regularly.
