Shorefins Air Driven Sponge Filter for Aquariums up to 20 Gallons - Keep Your Fish Tank Clean and Oxygenated

The Shorefins Air Driven Aquarium Sponge Filter by Penn-Plax is essential to a beautiful clean fish tank. The sponge filter provides efficient water filtration by using air from an air pump to create bubbles that rise through the sponge, driving water flow and helping to clean and purify your tank’s water. This Sponge Filter is ideal for Bettas and Shrimp as well as other smaller tank species as it can be used as primary or supplemental filtration and aeration - both vital for a healthy environment. Through both biological and mechanical filtration, the sponge filter encourages the growth of beneficial bacteria, which is essential for maintaining a healthy aquarium environment. Suitable for tanks up to 20 gallons, this air-driven filter improves water quality while ensuring proper aeration. Please note, the air pump is not included and is required for operation.

• AIR PROCESS: The Shorefins Air pump pushes air through the airline tubing causing bubbles to rise from the sponge and drives water flow through the filter for the purpose of cleaning and purifying water quality

• GALLON SIZE: Sponge filter can be used for small fish tanks and aquariums up to 20 gallons / 76 liters as the primary or secondary filter 
• NEEDS AIR PUMP: This air-driven sponge filter is powered by an air pump (Pump Not Included). We recommend the SAX7 Air Pump by Penn-Plax.
