How to choose the filtration system for Aquarium Big Fish Tanks?

When creating an ideal Aquarium Big Fish Tanks environment, the choice of filtration system is crucial. It not only affects the quality of life of fish, but also affects the beauty and stability of the entire aquarium landscape.
First of all, we need to understand the characteristics of large aquariums. The water body is large, and the number and variety of fish may be large, which means that the amount of waste generated is also large. Therefore, the processing capacity of the filtration system must be strong enough.
From the perspective of filtration methods, mechanical filtration is the basis. It can intercept solid impurities in the water, such as fish feces, leftover bait, etc., through media such as filter cotton. For large aquariums, it is necessary to choose filter cotton with moderate pores and durability, so that it can filter effectively without clogging quickly and affecting water flow. For example, some multi-layer filter cotton can intercept particles of different sizes in layers to extend the service life.
Biological filtration is a key link in maintaining stable water quality. In large aquariums, sufficient biological filter materials are needed to cultivate beneficial bacteria such as nitrifying bacteria. Ceramic rings, biochemical balls, etc. are common high-quality biological filter materials. They have a huge surface area and provide a good place for nitrifying bacteria to attach. Nitrifying bacteria can convert harmful substances such as ammonia nitrogen in water into relatively harmless nitrates. Moreover, when choosing biological filter materials, the quantity should be determined according to the size of the aquarium and the density of fish. Generally speaking, the more fish there are, the more biological filter materials are needed.
Chemical filtration is also indispensable in some cases. For example, when heavy metal ions or other harmful substances are present in the water, chemical filter materials such as activated carbon can be used for adsorption. However, chemical filter materials need to be replaced regularly to ensure their adsorption effect.
In terms of the type of filtration system, external filter barrels are the choice of many large aquarium enthusiasts. Its advantages are that it does not occupy the internal space of the aquarium, and it can accommodate more filter materials and has a good filtration effect. At the same time, some high-end external filter barrels also have a good mute effect and will not cause noise interference to the living environment. In addition, the bottom filtration system is also very suitable for large aquariums. It has a large filtration space, can hold a large amount of filter materials, and can more effectively collect impurities at the bottom by pumping water from the bottom.
In addition, we also need to consider the flow rate of the filtration system. Generally speaking, the filtration flow rate per hour should be 3-5 times the volume of the aquarium water body. For example, for a 1000-liter aquarium, the flow rate of the filtration system should be around 3000-5000 liters per hour. This ensures that the water can be fully circulated and filtered.
