Frequently Asked Questions

Q: Is an air pump included with the aquarium sponge filter?

Q: How often should I clean the aquarium sponge filter?

A: Cleaning frequency depends on your tank's bio-load, but generally every 2–4 weeks is recommended. Always rinse the sponge gently in room-temperature aquarium water (never tap or hot water) to preserve the beneficial bacteria living within the sponge media.

Q: What tank sizes is this bio-sponge filter compatible with?

A: The smaller size (6×10 cm) is well-suited for nano and small tanks, while the larger size (7.5×11 cm) works great for medium-sized aquariums and shrimp ponds. Always pair it with an appropriately sized air pump for best performance.
