The necessity of filtration in aquariums and aquariums
In the water body, not only some residual bait, corpses, secretions, excrement, protein, but also some invisible compounds and toxic nitrogen salts exist. The long-term existence of these compounds will inhibit the growth of fish or aquatic organisms. And cause disease. Most of these compounds are dissolved organic substances produced by natural biological decay.
Therefore, in an aquarium or aquarium, the water source should be filtered regularly, not only to remove some residual bait and excrement, but also to filter out some potential chemical substances. If this is not done, the fish will never grow into Normal adult size. This stunted growth will cause fish to never obtain the beauty of mature fish, and may cause other related health problems.
Therefore, the filtering system here is not only filtering garbage, but also filtering some invisible impurities in the aquarium.
