Aquarium sponge filter (Fish tank sponge filter)

The characteristics of this type of filters are:

Filter Sponge: The heart of the filter is porous sponges placed in a box inside the aquarium. This sponge acts as a filter media, trapping solid particles in the water as it passes through it.

Mechanical Filtration: solid particles suspended in the water, such as food debris, fish excrement and plant debris, are trapped by the sponge as the water flows through it. This helps remove visible debris from the aquarium, keeping the water clean and clear.

Biological Filtration: In addition to mechanical filtration, the sponge filter also provides considerable surface area for the growth of beneficial bacteria. These bacteria colonize the surface of the sponge and break down organic debris in the water, converting it into less toxic compounds such as nitrites and nitrates. This helps maintain a healthy aquatic environment for fish by breaking down toxic wastes.

Water Circulation: Water circulation through the sponge filter is usually provided by an air pump or an external water filter that sucks water through the filter. The air pump creates bubbles that rise through the sponge, pulling the water with them and creating a constant flow through the filter.

Maintenance: Sponge filter maintenance is relatively simple. On a regular basis, the sponges should be rinsed with aquarium water to remove trapped debris and maintain their effectiveness. This process should be done carefully so as not to completely remove the beneficial bacteria. In addition, it is advisable to replace the sponge every so often to ensure optimal filter performance.

In summary, an aquarium sponge filter provides an effective combination of mechanical and biological filtration to keep aquarium water clean and healthy for fish and other aquatic inhabitants. It is a popular choice among aquarium hobbyists because of its effectiveness, simplicity and low cost.

This model is designed to work with two conventional supermarket sponges, making it easier to get replacements. It is designed to use 2 sponges so that it is possible to interchange 50% of the biological filter material, going from a filter that has one sponge to the new filter. The only disadvantage of it is that the PPD of supermarket sponges is high compared to other alternatives.

Regarding the printing, the printing is designed to be done without supports with a printer with a good layer ventilation in PLA. The ideal would be to have biological material inside to give it a higher weight otherwise pebbles in the base and the same filter.
