Our Aquarium Sponge filter – 20 & 100 litre aquariums deliver efficient mechanical and biological filtration for tanks from 20 to 100 litres. They work well in shrimp tanks, fry tanks, or any freshwater or tropical setup. The air-driven design pulls water through the sponge, trapping debris while supporting a healthy colony of beneficial bacteria.
Aquarium Sponge filter – 20 & 100 litre aquariums are easy to Setup. First, rinse the sponge with tap water and squeeze out the excess. Then place it in the tank and let it sink naturally, or gently squeeze out the trapped air underwater for quicker sinking. Once running, the filter creates a gentle flow that protects baby fish, sensitive species, and small invertebrates.
Maintenance stays easy. Clean the sponge only with aquarium water to preserve the essential bacteria that keep your tank stable. Avoid tap water during cleaning because it can harm the biological filtration. With proper care, the sponge lasts a long time and keeps your water clear.
Available in sizes suited for nano, mid-size, or larger aquariums, these filters offer reliable performance and excellent versatility. They keep water clean, support healthy tank conditions, and provide safe filtration for even the most delicate aquatic life.
