Nuvo Roller Automatic Desktop Model 7420-A

The Innovative Marine NUVO Roller PRO Automated Fleece AIO Filter (Desktop Model, SKU: 7420-A) is a drop-in, motorized mechanical filtration system engineered specifically for nano and small-format reef tanks. Designed to slide directly into the first rear filtration chamber of all Innovative Marine NUVO Fusion Desktop All-In-One (AIO) aquariums, this unit completely automates your mechanical filtration and replaces traditional filter socks. 

By utilizing a time-cyclical micro-motor rather than prone-to-fail float sensors, it systematically extracts fish waste, organic detritus, and floating particles out of the water column before they can break down into nitrates and phosphates.

• Time-Based Cyclical Advance: Instead of relying on mechanical float switches that can easily get jammed by salt creep or snails, the 7420-A utilizes a digital timer. It is pre-programmed to automatically advance a fresh segment of fleece once every 12 hours.
• Adjustable Bioload Settings: The electronic controller features an "A" (Automatic) button that lets you cycle between three distinct bioload profiles based on your tank's stocking levels:

• Low (L): Automatically advances the roll for 8 seconds every 12 hours.
• Medium (M): Automatically advances the roll for 12 seconds every 12 hours.
• High (H): Automatically advances the roll for 16 seconds every 12 hours. 

• Space-Saving "Skimmer Ready" Profile: Designed with a ultra-compact footprint that perfectly fills the first overflow chamber while leaving the adjacent second rear compartment wide open to drop in a NuvoSkim DC Protein Skimmer.
• Fail-Safe Multi-Level Overflows: Features integrated bypass cutouts stacked at varying vertical levels. If a roll completely runs out or experiences a stall, water will naturally route around the fleece to prevent the rear chambers from drying out or overflowing your display tank.
• Premium Tool-Free Upkeep: Built entirely out of heavy-duty, reef-safe cell-cast acrylic with a polished black body and matching top cover to blend into the background. It features an inner pull-out tray and side-locking holders for seamless, tool-free fleece roll replacements.
