Product Introduction

This is a fish tank outlet that integrates water flow guidance with highly efficient oxygenation. Its unique inverted-cone chamber design leverages the Venturi effect to draw air into the water stream, generating a large number of fine, dense bubbles upon discharge and significantly boosting dissolved oxygen levels. The product can be directly connected to a filtration hose and secured to the tank wall using suction cups or hose clamps, making it ideal for small to medium-sized aquariums where optimized water circulation and increased oxygenation are required.

Design Highlights

1. Inverted-Conical Vortex Mixing Chamber: The core inverted-funnel-shaped structure creates a low-pressure zone inside, naturally drawing in air and vigorously mixing it with the water flow to produce a continuous, fine bubble stream. This delivers high oxygenation efficiency while operating quietly.
2. Adjustable Bent-Section Outlet: The blue flexible tubing allows users to freely adjust the discharge angle and direction, easily directing the bubble stream to specific areas of the tank—such as dead zones—to optimize water circulation.
3. One-Piece, Sturdy Body: The purple body is robust, seamless, and features smooth internal flow channels, effectively reducing water resistance and noise. It is durable and easy to clean.
4. Convenient Suction-Cup Installation: A built-in suction cup at the base ensures secure attachment to smooth tank walls. Installation and removal require no tools, positioning is highly flexible, and the tank surface remains undamaged.

Technical Specifications

• Compatible Hose Diameter: Universally compatible with hoses having an outer diameter of 12 mm (16/22 mm) or 16 mm (20/27 mm).
• Body Material: Suitable for 3D printing with PETG or ABS materials (safe for long-term underwater use).
• Core Functions: Oxygenation, water flow guidance, and bubble refinement.
• Installation Method: Suction-cup attachment or hose-clamp fixation.

Application Scenarios

1. High-Oxygen-Demand Fish Keeping: Provides ample dissolved oxygen for ornamental fish with high oxygen requirements, such as goldfish and bettas.
2. Supplemental Oxygenation for Planted Tanks and Eco-Aquariums: During nighttime or summer heat, it supplements oxygen in planted tanks to meet the respiratory needs of fish, shrimp, and microorganisms.
3. Small Tanks and Quarantine Tanks: Serves as the primary source of oxygenation and water circulation in small tanks without built-in filtration, helping maintain clean water quality.
4. Treatment Tanks and Breeding Tanks: During medicated baths or breeding periods, it provides a gentle yet abundant stream of bubbles to avoid startling broodfish and fry.
