AQQA Aquarium Sponge Filter – Submersible Foam Filter for Freshwater & Saltwater (20–110 Gallons)

Overview

The AQQA Aquarium Filter Sponge delivers ultra-quiet, air-powered operation designed to keep noise to a minimum while supporting clear, healthy water for your aquatic setup. Note: an air pump and air hose are not included; select a compatible pump sized to your tank for best results.

Efficient Mechanical and Biological Filtration

The sponge element provides mechanical filtration using a vertically patterned design that expands the filtration surface area, helping to trap debris and particulate matter as water passes through. Bio ceramic media balls support beneficial bacteria and contribute to biological filtration, aiding in the breakdown of waste products and supporting a balanced nitrification process in the aquarium.

Replaceable Media for Easy Maintenance

Both the foam sponge and the bio ceramic media are replaceable. The package includes two sponges and washable, reusable ceramic balls, with the flexibility to swap in alternative media to suit your needs and preferences.

Multi-Functional, Space-Saving Design

This compact unit combines filtration, aeration, and water circulation in one device, helping to maintain a clean tank environment while saving space inside the aquarium.

Wide Tank Applicability

Designed for versatile setups, it works well in fry tanks, shrimp tanks, Bettas, and both freshwater and marine environments. The small model targets 5–20 gallons, while the medium model covers 20–110 gallons. Ensure the sponge sinks fully by pre-saturation before placement.

What’s Included

• 2 replaceable filter sponges
• Bio ceramic media balls (washable and reusable)

Installation and Maintenance Tips

To start, squeeze the sponge underwater until it fills with water so the filter sinks correctly. Rinse sponges in tank water during routine maintenance and replace media as needed to sustain performance over time.

Important Note

Operate the filter with an air pump and airline tubing (not included). Choose a pump appropriate for your tank size to ensure adequate airflow and filtration.
