The closed Top fin filter only filters the bottom layer of the water. When the filter is kept closed, it can not filter all the depths at once. It only works on the lowest layer, which is just above the floor of the aquarium. 

But this will not cause any issues in keeping the tank clean. Many people will think that except for the bottom layer, the rest of the aquarium will be dirty. But that does not happen. Rather the entire tank is cleaned properly. Wondering how? Well, here is the reason. 

As mentioned earlier, there are waste products in almost every layer of the water. This happens due to the different densities of the waste particles. But as they are soaked in water, they start to get heavy. But why do they get heavy?

This happens due to the absorption of water by the particles. And once they are heavy, they do not stay at the same depth of water. Rather they fall to the floor of the aquarium. Sooner or later, all the particles will go down. 

And this is where the closed Top fin filter operates! As a result, the tank gets a thorough cleaning without much hassle.
