Product Introduction:

This is a 3D-printed modular corner filter designed specifically for small and ultra-small aquariums, particularly desktop round or square tanks. It ingeniously utilizes the otherwise unused space in the aquarium’s corners, combining physical filtration with biochemical filtration to achieve highly efficient water purification while occupying minimal footprint. The entire system is modular and highly flexible, with simple installation and removal, making it an ideal choice for creating a clean, healthy desktop aquatic ecosystem.

Design Highlights:

1. Innovative Corner Space Utilization: The unique fan-shaped quarter-circle design fits perfectly into the aquarium’s corner, virtually eliminating any encroachment on valuable viewing space—making it a revolutionary solution for filtering small and nano-sized tanks.
2. Modular Functional Configuration: The system consists of multiple functional modules, including a filtration chamber with densely packed filter holes (suitable for filter floss and bio-chemical media), a pump chamber with connection ports (for mounting a miniature water pump), and a high-density anti-siphon protection mesh. Users can freely combine these components based on their specific needs for “physical filtration–biochemical filtration–water circulation.”
3. Efficient and Quiet Water Flow Design: The densely spaced filter holes on the modules evenly disperse the water flow, minimizing stagnant zones; when paired with a built-in pump, they create stable water circulation while operating quietly—perfect for office or bedroom environments.
4. Sturdy Wall-Mounting and Anti-Siphon Structure: Certain components feature dedicated mounting flanges that securely clip onto the aquarium walls, ensuring overall stability. The high-density protective mesh effectively prevents small fish and shrimp from being sucked into the pump, providing safe and reliable operation.
5. Optimized 3D-Printed Structure: All components are specifically optimized for 3D printing, featuring a robust structure with a high success rate even without supports. The surface is smooth and easy to clean, and the parts are printed using aquaculture-safe materials, so long-term immersion poses no concerns.

Technical Specifications:

• Compatible Aquariums: Suitable for small square or round aquariums with side lengths or diameters ranging from 15 cm to 30 cm. Recommended for placement in the corner.
• Core Components: Includes a large fan-shaped filtration chamber, a small fan-shaped pump chamber with pump connection ports, and a high-density fan-shaped protective mesh, among other modules.
• Materials: Must be printed using aquaculture-safe, non-toxic PLA or PETG materials.
• Items to Provide: A miniature submersible pump (choose based on tank size; typically 3–5 W) and filtration media (such as filter floss or bio-balls).
• Printing Recommendations: We recommend a layer height of 0.2 mm, no supports required, and single-piece printing.

Application Scenarios:

1. Miniature aquariums—such as small desktop round tanks, square tanks, and thermoformed tanks—where traditional filters are difficult to install.
2. Open tanks or simply decorated tanks housing small species like bettas, guppies, tetras, and ornamental shrimp.
3. Office spaces, student dorm rooms, bedside tables, and other settings with strict requirements for space efficiency and quiet operation.
4. As a simple filtration and oxygenation device for breeding tanks or quarantine tanks.
