What to Compare Before Buying
- Tank size: This small version is stated for 5-91 L aquariums. Compare that with the size of your tank before choosing.

- Use case: It is described for breeding, fry, shrimp, snails and betta tanks, as well as pre-filtration or auxiliary use.
What Else You May Need
An air pump and airline are needed because the filter is air-driven and they are sold separately.
Care, Cleaning and Storage
The sponge should be washed about every 2 to 4 weeks, using tank water for rinsing. The filter container is detachable, and the sponge can be replaced with other filter media if needed.
Before You Decide
Confirm the small size, the 5-91 L tank range and the under-40 cm depth guidance before choosing an offer. Also check that you already have an air pump and airline, since they are required for use. If you need a larger aquarium version, the stated size and depth range are the key details to compare.
