The stainless steel filter is installed at the initial end of the fish tank filter

If you want to keep good fish at home, the fish tank filter is indispensable, but many people do not understand this very well. In the above article, I introduced the correct method of using the fish tank filter. In this article, I brought you the filtration method, you can understand. At present, the filter must have two or more filtration methods: physical filtration, biochemical filtration, chemical filtration, I will give you a detailed introduction to their information.

1, physical filtration: in simple and clear words, it is the use of mechanical methods to separate out the larger particles in the water. For example, the rest of the feed particles, dead fish bones, fish body excreta, secretions, vomit, body surface mucus, etc., generally use sponge, spray cotton, fine mesh stainless steel filter, palm leaf fiber, etc. It is usually set at the initial end of the filtration system for easy cleaning.

2. Biological filtration: the purpose of this filtration method is to cultivate beneficial bacteria and decompose harmful elements, such as ammonia salt, nitrite, nitrate, phosphate and so on, through bacteria. Commonly used filter media are: biochemical ball, ceramic ring, glass ring, coral sand, etc.

3, chemical filtration: it is the use of chemical agents to remove impurities in water, the use of the preparation of water stabilizer, flocculant, algal agent, protein decomposition agent, deodorant and so on.

4, adsorption filtration: it is wood, coal, fruit shells, animal bones and other substances with very high carbon content can adsorption seawater protein, trace elements, decolorization, in addition to odor, it is worth mentioning that even ozone molecules can be absorbed by it. It also absorbs fish urine, microalgae and drugs from the water. After reading the above information, you have some understanding of the filtration method of fish tank filter, and you need to pay attention to because nitrifying bacteria must live in the filter cotton, glass ring or bottom sand with flowing water, so the filter should be maintained for 24 hours.
