The Ultum Nature Systems Dual AIO Aquarium combines the clean, minimalist design of a rimless tank with the convenience of built-in filtration. Designed for both freshwater planted aquariums and saltwater reef setups, these all-in-one aquariums offer a streamlined solution for hobbyists who want performance and value aesthetics.

Available in a range of sizes, Dual AIO aquariums are practical and space-efficient options. Each tank includes filter media and a water pump for an easy, reliable start while still leaving room for customization based on your needs.

Like all UNS rimless aquariums, the DUAL AIO series features high-clarity glass, 45° mitered edges, and clean silicone work, ensuring the best views of your planted aquascape or nano reef.

Dual AIO Highlights
- Convenient Dual Use: Suitable for freshwater planted aquariums and saltwater nano reef setups. Whether you’re growing vibrant aquatic plants or nurturing softies, vivid LPS, and SPS corals, this system has you covered
- Complete Integrated System: Built-in filtration with included media and pump makes setup quick and easy without external equipment clutter
- Clean, Minimalist Design: Rimless edges with integrated rear chambers that can be customized further

Choosing Between Dual AIO or Standard Tanks
Dual AIO aquariums are ideal for hobbyists looking for a streamlined, ready-to-go system, while standard tanks are better for those who prefer full control over every component of their setup.

What’s Included
- UNS Dual AIO Aquarium
- Black leveling mat
- Media riser tray
- UNS Bio Block filter media
- Submersible water pump
- Outflow nozzle
- Back chamber lid

Filtration System Overview
Each Dual AIO aquarium features a multi-chamber rear filtration system designed to handle mechanical and biological filtration within the tank itself. Water flows through each chamber where media can be customized as needed, then returns to the main display tank. This creates a self-sufficient system that eliminates the need for external filters or additional plumbing. Dual AIO aquariums can also be expanded with a range of compatible accessories designed to upgrade system performance. Explore Dual AIO accessories here.
