AQQA Internal Aquarium Filter – Submersible 5-40 Gallon Filter with Wave Maker, Bottom Inlet & Quiet Pump

Meet the AQQA Internal Aquarium Filter, a compact, all-in-one filtration system designed for freshwater tanks from 5 to 40 gallons. Its fully submerged bottom intake means the pump stays underwater during water changes and evaporation, reducing the risk of dry-run damage and helping extend motor life.

One unit, multiple benefits

This versatile internal filter combines filtration, oxygenation, wave making, and water circulation. In a small footprint, it helps keep water clear and creates a dynamic current that supports aquatic life while minimizing maintenance needs.

• Bottom-intake design minimizes dry-running and protects the pump.
• Dual filtration with a bio sponge and activated carbon improves clarity and odor control.

Customizable flow, visible movement

Powered by a 300 L/H pump, the unit generates a lively current and tiny air bubbles that aerate the water. A flow-control valve lets you adjust intensity, while the rain-bar outlet ensures even distribution and a pleasing visual effect.

• Flow-control lets you tailor current for fish, plants, or decor.
• Even water distribution reduces dead zones and keeps debris in motion for easy removal.

Whisper-quiet operation and secure setup

Engineered for ultra-quiet performance, it runs under 30 dB. Four silicone cushions dampen vibration, making it suitable for bedrooms and living rooms. The compact, corner-friendly shape helps you fit the unit without clutter.

Simple care, reliable performance

Setup is straightforward: submerge, release trapped air, then plug in. Replace cartridges weekly for best results. The filter uses safe materials to protect sensitive species, and it is designed for freshwater use only.

Included support and warranty: AQQA backs this filter with a 3-year warranty and responsive 24/7 customer service to help with setup or questions.
