XY-2821 Large Aquarium Sponge Filter
The XY-2821 Aquarium Biochemical Sponge Filter is a reliable, air-driven filtration option for freshwater aquariums. Designed for gentle water movement and strong biological filtration, this large sponge filter is a great choice for fish tanks, shrimp tanks, fry tanks, quarantine tanks, breeding setups, and community aquariums.
Sponge filters work by pulling aquarium water through the porous sponge, helping trap debris while providing a large surface area for beneficial bacteria to grow. These beneficial bacteria help support the aquarium’s nitrogen cycle, making sponge filters a simple and effective way to improve water quality.
The XY-2821 is especially useful for tanks with small fish, fry, shrimp, or delicate species because it provides filtration without creating a strong current. It is easy to set up, easy to maintain, and works with an aquarium air pump and airline tubing.

Setup & Maintenance
Connect the sponge filter to an aquarium air pump using airline tubing. For best performance, use a check valve to help prevent water from flowing backward into the air pump. To clean, gently squeeze the sponge in removed aquarium water during a water change. Avoid rinsing the sponge under untreated tap water, as chlorine can harm beneficial bacteria.
