Dirk advertises on the Internet under the banner of "German Dirk", but it is difficult to relate it to the "German Dirk Aquarium Group" from the company's qualifications and trademark registration information, as well as the international trademark system. Despite this, the aquarium brand, which has reached a strategic partnership with JD.com, has seen strong sales on online shopping platforms and has become the top brand in the aquarium fish tank category in major shopping festivals in 2018.
 
In addition to being attracted by the "Made in Germany" advertised by the merchants, the price is close to the people and the complete supporting facilities are also important reasons for consumers to choose Dirk finished aquariums. Dirk's aquarium products are abundant, and players who are new to it are easy to feel dazzled. In fact, the brand's aquariums can be divided into two types: bullet aquariums and square aquariums according to their appearance, both of which use float glass. Dirk has also recently launched a series of acrylic aquariums that are smaller and aimed at entry-level users.
 
The so-called bullet is that one side of the aquarium is against the wall, and the glass on the other side is curved like a bullet. Dirk's finished aquarium contains a box, base cabinet, filtration system, filter material, pipe fittings, lighting sources and other appliances, which can be used immediately in principle, but in actual use, due to the low quality of the included equipment, players who want to pursue better breeding results often need to modify or purchase additional equipment. Taking the bottom filter of the bullet series as an example, the attached submersible pump and filter media have poor filtration effect, and the dry and wet separation device is also occasionally defective. Generally speaking, it is best to choose the bottom filter for players who breed large fish, while the side filter with a smaller size and less impact on the appearance is suitable for players who breed small fish and aquatic plants. Most of the aquariums in the bullet series are priced below 2,000 yuan, but the specific price depends on the size and configuration of the box.
 
Square aquariums are one of the most popular collections of Dirk, but they are not recommended. The reason is that although this series of main Arowana farming has a lower price than Butterfly and Black Diamond, it is relatively rough in design and technology, and the quality of the included equipment is not high, so veteran players can customize the aquarium that is more reliable and more in line with their breeding habits.
 
In contrast, the acrylic series priced at about 1500 yuan is more recommended. This novice aquarium is divided into cylindrical and cuboid styles, and the filtration system is available in two types: bottom filter and top filter, and comes with filter media, oxygen pump, sewage valve, lighting source and other appliances to meet the breeding needs of beginner players. Compared with Sensen's medium-sized aquarium of the same grade, Dirk's acrylic series is slightly lower, but due to the limitation of the material, the permeability of the glass is not as good as that of Sensen, which uses ultra-clear glass, and the included utensils are also far behind Sensen.
 
Overall, the Dirk Aquarium is a worthy option for novices to consider due to its affordable price and complete range of accessories. For slightly more advanced aquarium enthusiasts, Dirk has shortcomings such as unreasonable design, poor details and poor quality of supporting equipment, which is not satisfactory enough.
