Key Features

Automatic Roller Filtration
High-density fleece automatically advances when clogged, providing uninterrupted mechanical filtration without manual intervention.
Highest Compatibility in the Industry
Designed to fit various nano all-in-one aquariums including IM, Waterbox, UNS, Aquatop, AquaOne, AquaManta, HelloReef, and more. Highly reusable. See the tank fit guide below for details.
Supports Dual Mode
Supports synchronized operation of two filters with a single controller—ideal for dual-chamber setups or tanks with a high bioload.
Freshwater and Saltwater Compatibility
Built for reliable, long-term performance in both freshwater and marine aquarium environments.
FDA Food-Grade Fleece Rolls
Industry-first! Fleece rolls are made from FDA food-grade material and independently tested by a certified third-party laboratory to comply with U.S. FDA food-contact standards (21 CFR 177.1630).

Main vs Extension

The extension unit does not include a power adapter, controller, or sensor. A dual-link cable is included. It must be connected to a main filter controller to run in sync mode, and both motors advance together when the main sensor triggers. A dual-filter setup is highly recommended for aquariums with two filter chambers, especially systems above 25 gal / 95 L, though a single main filter will still work better than filter socks.

⚠ Fleece Roll WarningPlease do not use third-party fleece rolls. Differences in roll length, width, and thickness can place significantly different loads on the motor. Improper rolls can damage the motor and body, and any resulting damage will void the warranty.
