• How Does the Sponge Filter Works?
• 1. A sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge. As water is drawn out through the lift tube or pump, it is replaced by water entering the sponge.
• 2. Suggest replacing the bio-foam every 6 months, to ensure the filtering effect as well as the growth of the nitrifying bacteria.
• 3. Before use, soak the bio-foam in aquarium water for 5 mins.
• 4. During maintenance, always rinse the bio-foam with drained-out aquarium water only. No tap water or hot water should be used at all.
• 5. When re-using the bio-foam, do squeeze the foam in the water to remove all trapped air bubbles. This will keep the filter stay submerged.
