In the process of fish farming, filter cotton is an important tool. There are different types of filter cotton, their material is different, so its effect is also quite different. Common materials are synthetic fiber filter cotton, sponge, white cotton, two-color cotton and so on. These are more commonly used, each has its own advantages and disadvantages, so when choosing, you can choose according to your own needs. Different standards, the choice of filter cotton is also different.
For example, the price of two-color cotton will be cheaper, and the practicability is stronger, the filtering effect is better, but it may be deformed after several times of use, so it needs to be replaced regularly. The same is true of white cotton, although the texture is fine, the filtering effect is good, and the price is relatively cheap, but the same cleaning time will be deformed, need to be replaced in time. Sponges are different, they are easy to clean, can be reused, do not need to be replaced frequently, but the filtering effect will be worse. In short, the requirements are different, the standards are different, and the types of filter cotton recommended are also different.
In the use of filter cotton, they will become dirty, so regular cleaning is an important issue. After they are really dirty or deformed, they need to be replaced, otherwise their filtering effect will be greatly affected. However, generally speaking, it does not need to be replaced frequently, so the cost will be higher. Different materials of filter cotton replacement frequency is also different, such as synthetic fiber filter cotton can be changed once a month or so, polyester foam can be changed once three months or so.
