How Does Sponge Filter Work?
The sponge filter has been there for a long back. It is a great tool to filter out dirt residue or unwanted particles in an aquarium (fish tanks). It is pretty simple and efficiently keeps the aquarium clean. Most people doubt the performance of the filters as they find this simplicity too good to be true. This is the reason most people go for more complex filtering material options. But trust us, a sponge filter is enough for keeping your aquarium clean and healthy.
