Fish Tank Air Pump with Multifunctional Biochemical Sponge Filter for Small Aquariums

A compact, all-in-one filtration and aeration solution designed for tiny aquariums. It combines mechanical and biological filtration with efficient aeration, helping keep water clear and reducing the need for frequent water changes in nano tanks, betta setups, shrimp habitats, and other small aquatic spaces.

• Compact, space-saving design: Mini footprint fits neatly into small aquariums without crowding décor or swimming space.
• Multifunctional filtration: Combines mechanical filtration via the biochemical cotton with a biological filtration process that hosts nitrifying bacteria to break down waste.
• Enhanced aeration: Bubble stones improve dissolved oxygen levels, supporting healthier fish, shrimp, and plants while promoting gentle water circulation.
• Biochemical filtration media: Water first passes through the middle of the filter cotton for physical filtration, then benefits from microbial action that helps decompose contaminants.
• Easy setup and operation: Simple two-step use—connect to an air pump with tubing and power on; water outlet or bubbling indicates normal operation. A check valve is recommended if the air pump sits lower than the water level.

This device is ideal for hobbyists managing nano tanks, betta bowls, shrimp habitats, or fry rearing tanks where space is limited but reliable filtration and oxygenation are essential. It helps maintain clearer water with less frequent water changes by fostering a productive nitrifying bacterial ecosystem alongside physical debris removal. For best results, pair with regular monitoring of water parameters and occasional maintenance of the filtration media to sustain a healthy, stable aquatic environment.

SPECIFICATIONS

Brand Name: NONE

Choice: yes

High-concerned chemical: None

Origin: Mainland China

Type: fish

Product features:

1. Strong filtering ability, keeping water clear for a long time and reducing frequent water changes;

2. Decompose excrement into small particle molecules and absorb them back into biochemical cotton to cultivate a nitrifying bacterial system;

3. Filtering bubble stones can increase the solubility of oxygen in water;

4. Exquisite and mini, occupying no space, suitable for use in various small fish tanks;

5. The airflow of the oxygenation pump comes out from the small hole at the bottom of the water fairy. Because the water fairy's pipeline is relatively thin, bubbles swarm upwards in the pipeline, which exerts a thrust on the water inside the pipeline, causing the water flow to circulate;

6. The inlet of the water flow is in the middle of the biochemical filter cotton. After passing through the biochemical filter cotton, the water flow has a preliminary physical filtration effect. The feed and paper scraps in the fish tank are left behind by the biochemical filter cotton. Then, there are microorganisms such as nitrifying bacteria on the biochemical filter cotton that will further decompose the filtered dirt.

Usage:

1. Connect this product to the air pump using a trachea

2. Plug in the air pump to the power supply, and the product's water outlet (or bubbling) indicates normal operation.

Attention: If the air pump is lower than the water pump, please install a check valve
