Product Overview

This product is a modular activated-carbon filtration canister specifically designed for small aquariums. It features a cylindrical body with a detachable top cover, allowing the interior to be filled with activated carbon and other filter media. The dense array of holes in both the canister wall and the top cover ensures efficient water flow, effectively adsorbing harmful substances, pigments, and odors from the water. It can be used as a standalone filtration unit or integrated into an existing filtration system, making it a practical purification tool for improving water quality in small aquariums and breeding tanks.

Design Highlights

1. Modular, Detachable Design: The main canister and the top cover are connected via a screw-on or snap-fit mechanism, enabling quick and easy opening and closing. This greatly simplifies the processes of loading, replacing, and cleaning the activated carbon.
2. High-Efficiency Dual-Zone Water-Flow Structure:
   • Canister Body: The sides are densely perforated with uniform grid-like or lattice-shaped elongated slots, providing a large effective water-flow area to ensure thorough contact between the water and the internal activated carbon.
   • Top Cover: Features a solid center with radially arranged peripheral openings, which prevents filter media from leaking out while guiding the water flow to disperse evenly and reducing short-circuiting of the flow.
3. Stable Stacking and Series Connection Interfaces: The standardized cylindrical shape and interface design allow multiple filtration canisters to be stacked vertically (creating multi-layer filtration) or connected in series horizontally, accommodating varying flow rates and purification requirements with high scalability.
4. Optimized for 3D Printing: The simple structure with no internal overhangs makes it ideal for 3D printing using materials such as PLA and ABS, and it is easy to post-process to achieve watertight sealing.

Technical Specifications

• Material: PLA or ABS suitable for 3D printing (environmentally friendly, non-toxic materials are recommended)
• Primary Dimensions (Approximate): Canister diameter about 5–6 cm, height about 7–8 cm (exact dimensions can be measured precisely from the model file)
• Filter Media Capacity: Can hold approximately 100–150 ml of activated carbon (particle size about 2–4 mm)
• Compatible Water Hose: The central hole in the top cover accommodates flexible tubing with an outer diameter of about 8–10 mm (for inlet or outlet connections)
• Installation Method: Can be submerged at the bottom of the tank, attached to the tank wall, or connected to an external filtration system

Application Scenarios

• Small Finished Tanks/Unfurnished Tanks: Serves as an auxiliary chemical filtration unit to adsorb yellowing, residual medications, or unpleasant odors, quickly improving the visual quality of the water.
• Breeding Tanks/Treatment Tanks: After medicated baths, the activated-carbon canister rapidly adsorbs residual drugs, creating a safe environment for fish recovery.
• Fine-Tuning Water Quality in Planted Tanks: Used to adsorb excess fertilizers or impurities in the water, helping to stabilize water quality and prevent algal blooms.
• Integration into Open-System Filtration: Easily connects to the outlet lines of drip boxes, top-mounted filters, or filter barrels as the final stage of purification.
