Frequently Asked Questions

Q: Does this mini aquarium sponge filter come with an air pump?

A: No, the air pump is not included. This package contains 1 complete aquarium sponge filter unit. You will need a separate air pump and airline tubing to operate the filter. Most standard aquarium air pumps are compatible.

Q: What size fish tank is this biochemical sponge filter suitable for?

A: This compact sponge filter is specifically designed for small and nano aquariums. Its small dimensions (2cm × 3cm × 9cm) make it ideal for tanks where space is limited, such as betta tanks, shrimp tanks, or small community fish tanks.

Q: How do I clean the sponge filter?

A: To clean the sponge filter, gently remove it from the tank and rinse the sponge sleeve in a bucket of aquarium water (not tap water) to preserve the beneficial bacteria colonies living in the sponge. Avoid using soap or harsh chemicals, as these can harm your fish.

Q: Is this aquarium filter quiet during operation?

A: Yes! This mini sponge filter is designed for silent operation. The noise level depends largely on the air pump you pair it with — choosing a low-noise air pump will result in near-silent filtration for your aquarium.
