Aqua-Fit Aquarium Sponge Filter

Description

This filter provides mechanical and biological filtration for easy aquarium maintenance. It uses an air-driven system to create suction that allows the sponge to capture floating particles in the water and return filtered water to your tank. 

To use:

1. Before use, soak the sponge in aquarium water for 5 minutes.
2. During maintenance, always rinse the sponge with drained aquarium water only. No tap water should be used at all.
3. When reusing the sponge, squeeze the foam in water to remove all trapped air bubbles. This will allow it to sink.
4. Replace the sponge every 6 months to ensure the filtering effect.
