This kind of drum adopts upper filtration, which is pumped by submersible pump to the upper filter box and then filtered by filter cotton in the box.
I don't want to criticize this tank, and I don't mean to belittle it.
Both novice and veteran can't raise fish well because of the poor filtration system.
There are too few cotton filters and the design is unreasonable. I don't want to say anything else, but the landlord will know how easy it is to die fish often.
The landlord pays attention to this fish tank of our company. As a classic design with many years of experience, it has been protected by national patents, and its efficient filtration system is incomparable to ordinary small fish tanks on the market.
I also hope that more novice friends will take fewer detours and raise fish happily.
