1. Why adding filter sponge into aquariums? Adding a filter sponge to an aquarium is a common practice in the hobby for several beneficial reasons. Filter sponges serve as a mechanical and biological filtration media, improving the overall water quality and creating a healthier environment for the aquarium inhabitants. Here are the main reasons for using a filter sponge: Mechanical Filtration: Filter sponges have a porous structure that helps trap and remove large particles, debris, uneaten food, and fish waste from the water. By doing so, they prevent these pollutants from breaking down and affecting the water quality negatively. Cleaner water not only looks better but also reduces the chances of harmful spikes in ammonia and nitrite levels. Biological Filtration: The surfaces of filter sponges provide ample space for beneficial nitrifying bac to colonize and establish a biofilter. These bac convert harmful ammonia (produced by fish waste and decaying matter) into less harmful nitrites and then further break down nitrites into relatively harmless nitrates. This biological process, known as the nitrogen cycle, is crucial for maintaining a stable and safe aquarium environment. Safe Habitat for Baby Fish and Shrimp: The dense structure of filter sponges can serve as a safe haven for baby fish and shrimp, protecting them from being sucked into the filter intake or becoming prey to other tank inhabitants. Reducing Flow for Gentle Water Movement: In some cases, filter sponges can be used to reduce the flow rate of a filter, which is beneficial for aquariums with sensitive fish or invertebrates that prefer calmer water conditions. Seeding New Filters When starting a new aquarium or setting up a new filter, using a piece of established filter sponge from a matured aquarium can speed up the cycling process. The beneficial bac already present on the sponge can quickly colonize the new filter media, helping to establish a stable nitrogen cycle faster.
