Which filter cotton in fish tank has good filtering effect?

Which filter cotton has a good filtering effect as follows:

1. Synthetic fiber fish tank filter cotton

This kind of filter cotton has soft texture, fine screen, high density and fine filtration.

sponge

This kind of filter cotton can filter the dust in the air, which is also called dust-proof fish tank filter cotton. Its density is not as big as the first one, but its advantage is that it is easy to clean and can be used repeatedly.

3. Biochemical cotton

This kind of filter screen is relatively large and suitable for relatively large impurity particles. Because the mesh is relatively large, the amount of water produced is relatively large, which is suitable for fish to lay eggs. Its advantages are easy cleaning and long-term use.

4. White cotton

The price is cheap, the texture is soft and the filtering effect is quite good. However, due to the delicate texture, it may be a little laborious to clean, and it may be deformed and rotted after cleaning.

5. Two-color cotton

The appearance is generally green on the top and white on the bottom, which is cheap and practical and has good filtering effect, but the filter fiber may be deformed after several times of cleaning.

No matter what kind of fish tank filter cotton, it should be breathable. Each kind of fish tank filter cotton has its own advantages and disadvantages, and its application is slightly different. But I think if you are a person who likes to raise fish at home, it is the best choice to use biochemical cotton and sponge together. The two complement each other and cooperate with each other to achieve the best effect. Good filterability, low price, great change of water quality and long service life. Besides, we can choose what we need according to our actual situation.
