How to choose aquarium filter cotton?

Physical aquarium filter cotton, as the name suggests, is a filter material used to achieve physical filtration effects, blocking feces, food residues, harmful substances, etc. from entering the fish tank again with the water circulation. Therefore, the physical filtration of filter media is generally small, with poor permeability, and mostly on the upper layer of filter media. Cotton filter: a commonly used physical filter material that can filter residue to a certain extent. The advantage is that it has a higher porosity and can also cultivate bacteria, resulting in better water permeability. The disadvantage is that the porosity is high, the filtration effect is not good, and it cannot be reused and needs to be replaced frequently.

Cotton filter is a basic and highly utilized filter material. Regardless of the type of filter, it is essential. Its main function is to filter the waste residue after filtration.

Biological aquarium filter cotton is a substance that exists for cultivating nitrifying bacteria. The presence of nitrifying bacteria can help decompose harmful substances in water tanks, purify water quality, and reduce physical filtration pressure. The selection of biological filter material first depends on its breathability, whether it can adhere to nitrifying bacteria to a large extent, and then whether the material is easy to pulverize. Filter materials that are easy to pulverize need to be replaced frequently, which is not conducive to long-term use and can also pollute water quality.

After using aquarium filter cotton for a period of time, it will attach a lot of dirt, and after several washes, it will shrink into a ball. Many may not be able to use the filter cotton in less than a month, so they have to replace it. In fact, cleaning filter cotton can greatly improve its service life by paying attention to the following three points:

Firstly, when buying aquarium filter cotton, be sure to buy the type without glue. Some filter sponges are ugly and will stay in the water for a long time, but your water may have foam, which is harmful to fish.

When cleaning the aquarium filter cotton, use the original cylinder water for cleaning. Because using the original water tank to clean the filter cotton reduces the loss of beneficial bacteria and can extend the interval between cleaning the filter cotton. If such conditions are not met, tap water can be put back into the water tank to drip nitrifying bacteria.

Aquaculture filter cotton is divided into several materials: synthetic fiber, polyester foam, and bio cotton. Among them, bio cotton has a longer lifespan and will not deform no matter how it is washed. It can be repeatedly rinsed and used. Non adhesive filter cotton has fewer chemical components and is beneficial for both fish and water quality. Therefore, people do not want convenience and economy. It is a good filter cotton that is beneficial for both fish and water quality.

Many friends may not be clear about the difference between bio cotton and filter cotton. Filter cotton and bio cotton are important components used in filtration systems, and many people can easily confuse them. However, if not strict, both can be made public, and the difference in their use is not significant.
