All-In-One (AIO) Box Kit (4th Gen) 75 Gallon Standard - Fiji Cube

The Fiji Cube All-in-One (AIO) Filter Box DIY Kit for the 75 Gallon Standard tank is a powerful conversion system designed to transform large, non-drilled aquariums into high-performance AIO filtration setups. This product represents the 4th Generation of the AIO DIY series, offering enhanced stability and maximized filtration capacity for demanding aquarium environments.

This All-in-One Filter Box provides a comprehensive, multi-chamber rear sump solution that integrates seamlessly into the back of a standard 75 Gallon aquarium (compatible with brands like Marineland, Tetra, and Aqueon). By relocating all filtration components—such as the heater, protein skimmer, and media—into the concealed rear chamber, the kit ensures an uncluttered, clean display view while maintaining superior water quality. It is a cost-effective and highly functional choice for setting up saltwater reef, freshwater, display, hospital, or frag growth tanks.

Key Features & Benefits

• Designed for 75 Gallon Standard: Perfectly sized to fit the dimensions of standard 75-gallon glass aquariums.
• Maximized Filtration: Multi-chamber design provides extensive real estate for mechanical (via filter sock), chemical, and biological filtration equipment.
• Uses 4-inch Filter Socks: Provides effective particulate removal and clarification of water.
• Clean Aesthetics: Eliminates the need for hang-on-back filtration, preserving the clean look of the main display.

Installation Requirement (4th Gen)

This 4th generation kit requires a permanent silicone seal for secure installation. The older generation's magnets and clamps are no longer provided, mandating that the unit be permanently bonded to the back glass of the tank with aquarium-safe silicone (not included).

Included in the AIO DIY Kit

The kit provides the core components for the AIO conversion:

• Fiji Cube All-in-One Box (Acrylic filtration unit)
• Filter Sock Holder with an included Filter Sock
• Plumbing Kit with an Adjustable Return Nozzle

Specifications (SKU: IB-75)

Note: The water pump, glass aquarium tank, silicone sealant, and the Fiji Cube Modular Media Basket (this kit is not compatible as it uses 4" socks) are not included and must be purchased separately.
