Seaoura SR-702A Small Internal Aquarium Filter

Q1: What type of filtration system does this aquarium filter use?
A1: This filter uses a dual-core filtration system that combines physical and biological filtration. It effectively removes solid waste, such as fish excrement and uneaten food, while cultivating beneficial bacteria, thereby creating a healthier aquarium ecosystem.

Q2: What filter media does this product include?
A2: It comes equipped with high-quality bio-sponge and bio-ceramic rings. You can also replace the ceramic media with other types of filter media based on your water quality needs.

Q3: Does this filter help increase the oxygen content in the water?
A3: Yes. It features two water flow modes: rain-style flow and aeration flow. Both modes help increase dissolved oxygen levels, thereby boosting fish vitality and improving the overall aquarium environment.

Q4: Is this filter noisy when running?
A4: Not really. It features a quiet-running design to ensure quiet operation. You may hear a slight bubbling or hissing sound only when the aeration function is in use, which is normal.

Q5: Is this filter suitable for beginners to install?
A5: Yes, it’s perfect for beginners. All parts are removable and can be easily assembled without specialized tools. Additionally, it comes with strong suction cups that securely attach the filter to the inside wall of the aquarium.

Q6: What is the correct installation depth for optimal results?
A6: For the best aeration results, we recommend installing the filter approximately 1.2 inches (about 3 centimeters) below the water surface. If installed too deeply, the aeration effect may be reduced, and it will primarily serve to circulate the water.

Q7: Can the internal filter media be adjusted or replaced?
A7: Yes, the internal structure is flexible. You can replace or upgrade the bio-ceramic filter media with other filter materials to suit different aquarium conditions and water quality requirements.
