The review covers various aspects, from initial unboxing and setup to its performance in maintaining water quality and the ease of its maintenance. Key features examined include its flow rate, biological filtration effectiveness, and the added benefit of integrated pothos roots.The Aqqa filter's performance is assessed in terms of its suitability for different tank sizes and the necessity of supplemental filtration. The reviewer carefully considers its strengths and weaknesses, providing practical advice on its optimal usage, including whether it's best suited as a primary or supplementary filter. Ultimately, the review aims to determine if this affordable filter provides a worthwhile investment for aquarium enthusiasts looking to improve their water quality without breaking the bank.
Pros And Cons
- Includes an electric pump, eliminating the need for a separate air pump.
- Comes with two extra sponges.
- Moves 80 gallons of water per hour.
- Provides good biological filtration, keeping ammonia levels low.
- 80 gallons per hour is insufficient for a 50-gallon tank on its own; additional filtration is recommended.
- May not provide sufficient mechanical filtration alone, leading to floating debris in the tank.
- May still require weekly water changes due to high nitrate levels.

Unboxing and First Impressions
The Aqqa sponge filter arrived promptly after ordering it on Amazon for around $23. The packaging was simple but effective, protecting the filter during transit. Immediately noticeable was the inclusion of two extra sponges, a welcome addition that shows some foresight by the manufacturer. This suggests a commitment to longevity and ease of maintenance, though the true test would be their durability over time.


How it Works and Water Flow
The filter's mechanism is straightforward. Water is drawn in through the bottom, passing through the filter media housed within. Then, it's expelled through two small pipes at the top, creating a gentle current within the aquarium. The manufacturer claims a flow rate of 80 gallons per hour, a decent rate for smaller tanks. However, for larger aquariums, it might not be sufficient on its own.

Filtration Performance and Maintenance
While the 80 GPH flow rate may be inadequate as a sole filtration system for larger tanks, its biological filtration capabilities are impressive. The reviewer noted significantly improved water quality, with ammonia levels remaining low. The primary water change needs were due to nitrate build-up, manageable with regular partial water changes. The included extra sponges are a lifesaver for maintenance, ensuring uninterrupted filtration when cleaning is necessary.


Additional Features and Considerations
One interesting addition was the use of pothos roots integrated into the filter media. The reviewer stated this addition further enhanced nitrate reduction. While this is a helpful addition for biological filtration, the Aqqa sponge filter is not designed for mechanical filtration. Consider supplementing this filter with a hang-on-back filter to address debris removal and ensure optimal tank cleanliness.

Final Verdict
The Aqqa sponge filter is a budget-friendly option that delivers surprisingly effective biological filtration. Its strength lies in its ability to keep ammonia levels low, improving overall water quality. However, its limited mechanical filtration warrants pairing it with a secondary filter for best results. Overall, it's a good value for money, particularly for smaller tanks or as a supplemental filter in larger setups. The included extra sponges make maintenance easy and contribute to the filter's long-term usability.
