I believe many friends use fish tank filter cotton or basically keep fish. But with so many people in the market, it's unclear how to choose. Today, the editor will briefly summarize the fish tank filter cotton for everyone.

Classification of fish tank filter cotton

Although there are various types of filter cotton, it not only plays an important role in ornamental fish farming, but also in water quality filtration. But there are two simple categories for fish tank filter cotton.

1、 Fish tank filter cotton - physical filter cotton

Mainly used for filtering feces and food residues from ammonia nitrogen sources in fish tanks. Because these substances are filtered, their density is naturally higher, and some residues are not easy to escape, resulting in poor filtration efficiency. There are many colors on the market, such as blue and green, but the classic one is white. Some names sound good, such as magic carpet, magic bag, PP cotton, which are essentially physical filter cotton. Dense physical filter cotton.

2、 Fish tank filter cotton - biochemical filter cotton

This type of cotton is mainly used for cultivating nitrifying bacteria, and its density is not as high as physical filter cotton. Its internal expansion is a porous structure, typical of rattan cotton, with a relatively large thickness, just to allow more places for nitrifying bacteria to breed and expand the population. However, it should be noted that both biochemical filter cotton and physical filter cotton have the function of cultivating nitrifying bacteria, but the structure of biochemical filter cotton is more suitable for the large-scale reproduction of nitrifying bacteria. In the filtration system, the more nitrifying bacteria decrease, the better.

How to scientifically place filter cotton in a fish tank.

First, let's take a look at the working principle of the fish tank filter cotton. Simply put, fish tank filter cotton allows water to flow through and leaves behind "dirty things". We can put it in the filter tank like this:

Upper filtration: Due to the small space, the filter material (such as ceramic ring) is placed at the bottom, and the second layer of biochemical filter cotton and the top layer of physical filter cotton are placed. When changing water, simply lower the top layer of the physical filter cotton.

Drip box: This type of space is relatively large and was originally designed for large-area filtration. But more space is used for stacking filter materials, only one or half boxes are used to place filter cotton. According to the same principle, the biochemical filter cotton is placed in the middle, and the physical filter cotton is placed on the top for easy cleaning.

Layered drip box

Filter cartridge: Its principle is similar to that of a drip box, except that the water flow rate is relatively fast, the water output is relatively large, the water droplets infiltrate slowly, the water flow is moderate, and the impact force of the water flow inside the filter cartridge is relatively large. Therefore, the placement principle is the same as that of the drip box

Bottom filtration: This filter has a strong filtering effect. Several segmented cylinders are used to fill the filter material. The arrangement order of filter cotton and filter material is as follows. Near the water outlet is the physical filter cotton, followed by the biochemical filter cotton, and finally the filter material. Because it is a water outlet, it is relatively dirty, so it is first physically filtered out for easy cleaning. Then, some substances in the water pass through the filter material and are treated by nitrifying bacteria. Our main products include fish tank filter cotton, primary filter, medium efficiency bag filter, primary efficiency plate filter, spray booth filter cotton, glue spray cotton, aquarium filter cotton, flame retardant filter cotton, activated carbon, etc. Welcome to contact us.
