What is the best filter for a grass tank (What filter is best for a home fish tank)

What methods can be used to filter the grass tank

Generally speaking, when choosing a filtration system for a water planted tank, the first principle is to make it as beautiful as possible, and the secondary option is its filtration effect. Common filtration systems today include waterfall wall-mounted filtration, filter barrels, external filter barrels , etc.

Waterfall wall filter

Especially for aquariums with a size of 40 cm or less, this waterfall-style wall-mounted filtration method will be chosen . The assembly is also very simple. After assembling according to the instructions, just hang it directly on the side of the fish tank.

Moreover, the general waterfall-style wall-mounted filter also has an oil film removal design. When you use some oily feed to raise fish, you don’t have to worry about the oil film covering the water surface and failing to create a shimmering visual effect.

Although this type of filtration looks good, it also has obvious disadvantages. Because the filter tank is very small, there is not much space to put the filter material. In addition, waterfall wall-mounted filtration is generally equipped with its own filter sheet, so it is basically impossible to add a filter tank by yourself because there is not enough space.

These filters are mainly filled with small white cotton and activated carbon, so the effect of cultivating nitrifying bacteria is not particularly good. Therefore, the task of cultivating nitrifying bacteria is mainly left to the bottom sand of the fish tank to complete.

Filter barrel

The filtering effect of the filter barrel is much better than that of the wall-mounted filter, because the space is increased many times, and physical and biochemical filtration can be well configured. However, it needs to be used with a submersible pump, so there are more pipes. In addition, the submersible pump will also take up part of the space in the fish tank, which is relatively not so beautiful.

The filter barrel is more suitable for larger fish tanks, such as those with a size of 60 cm or more . This way, the water flow from the filter barrel has enough space to buffer, and the water flow in the entire fish tank will not be turbulent. Of course, this is also related to the power of the water pump. The more powerful the water pump, the stronger the water flow.

External filter barrel

This type of filtration was developed later and has become more popular in recent years. The filtration effect is between waterfall filtration and filter barrel filtration, and it can be said that it has the advantages of both. However, it has not reached the pinnacle of the advantages of both, that is, it has the characteristics of both beauty and relatively good filtration effect .

The external filter barrel is the same as the filter barrel, with layered filter tanks inside, which can also form a complete filtration system, but the space is naturally smaller than the filter barrel.

Generally speaking, aquatic plant tanks do not require a very powerful filtration system, so from actual tests, this external filter barrel has a very good filtering effect on aquatic plant tanks.

At the same time, it is also like a waterfall wall-mounted filter, which can be hung directly on the side of the fish tank. There are not too many extra pipes, and the water pump is also built in. In this way, there is no need to put it in the fish tank separately, and it is also very beautiful. The only problem is that the power of the water pump is constant and cannot be adjusted and replaced directly.
