Aquarium Sponge Filters

Shop aquarium sponge filters for gentle mechanical and biological filtration in fry, shrimp, breeding, quarantine and community tanks. Most traditional sponge filters are air-driven and require a suitable air pump, airline and often a non-return valve, sold separately unless stated.

Choose a filter size and airflow suited to the aquarium and livestock. Aquaholics supplies sponge filters across Australia and provides local aquarium support from Baringa on the Sunshine Coast.

How Sponge Filters Work

Air rising through the lift tube draws aquarium water through the sponge. The sponge traps some debris and provides surface area for beneficial bacteria, while the bubbling also promotes water movement and gas exchange.

  • Gentle intake makes sponge filters popular for many fry and shrimp setups.
  • Established sponges can provide valuable biological filtration.
  • Airflow can often be adjusted with an airline valve or suitable pump control.
  • A sponge filter may be used alone in a lightly stocked tank or as supplementary filtration in a larger system.

Choosing a Sponge Filter

Tank and Livestock

Match the filter’s physical size and stated capacity to the aquarium. Very small fry may benefit from gentle airflow, while larger or more heavily stocked tanks may need additional filtration.

Single or Dual Sponge

Dual-sponge designs provide extra sponge area and can make staged cleaning easier. Single-sponge units are compact and may suit smaller tanks.

Air Supply

Check whether an air pump, airline, non-return valve and flow control are included. Select the pump for the water depth and number of air-driven devices.

Use and Maintenance

When the sponge becomes clogged or flow falls, gently squeeze or rinse it in aquarium water removed during a water change. Avoid cleaning every established sponge or biological filter in the system at the same time.

Keep the airline and lift tube clear, position the non-return valve correctly where used, and follow the air-pump manufacturer’s installation advice.

Complete Your Setup

Complete the setup with an air pump, airline tubing and other aquarium filtration equipment.

Frequently Asked Questions

Do sponge filters need an air pump?

Most traditional sponge filters do. Check the listing because an air pump, airline and valve may be sold separately.

Are sponge filters suitable for fry and shrimp?

Their gentle intake makes them a common choice, but airflow, sponge pore size and the particular livestock still need to be considered.

Do sponge filters provide biological filtration?

Yes. Once established, the sponge provides surfaces for beneficial bacteria as aquarium water passes through it.

How often should a sponge filter be cleaned?

Clean it when debris buildup reduces flow or performance. The interval varies with tank stocking, feeding and sponge size.

Can I run a sponge filter with another filter?

Yes. Sponge filters are often used as supplementary biological filtration, backup filtration or gentle filtration in addition to another filter.
