explain:
Product Name: Aquarium Sponge Filter
Color: Black
Reminder: the filter cotton can be compressed. If you receive deformed foam and let it soak in water, it will quickly restore its shape (please do not start an argument).
Reminder:
Soak the sponge in aquarium water for 5 minutes before use, as this will help nitrifying bacteria to more easily colonize.
2. Always rinse the sponge with aquarium water at room temperature, do not use hot water.
3. It must be used by connecting an air pump.
