400 Gallon All-in-One Aquarium with Stand, Built-In Wet-Dry Sump & 2000 GPH Pump | Ultra Clear Low-Iron Tempered Glass Fish Tank — Saltwater & Freshwater Ready, All Black

The Aquadream 400 Gallon All-in-One Aquarium in All Black bridges the gap between the 250-gallon and 500-gallon systems in the Aquadream lineup, delivering serious display capacity, professional-grade filtration, and the bold all-black aesthetic in a system sized for advanced home hobbyists, dedicated fish rooms, and commercial installations where scale matters but 500 gallons is more than needed.

The 282-gallon display tank is constructed from rimless, low-iron ultra-white tempered crystal glass with over 91.5% light transmittance, providing a near-colorless, high-clarity view of your aquascape across a 91-inch length and 31-inch height. Every panel is bonded with German high-endurance biophilic silica gel rated for up to 20 years of saltwater erosion resistance. At 0.59 inches thick, the glass delivers strong resistance to the impact, chemical exposure, and structural stress of daily use in a saltwater or freshwater environment.

The 132-gallon wet-dry sump, housed inside the all-black aluminum cabinet, provides comprehensive biological and mechanical filtration with a modular filter media divider system, giving you full control over your filtration media configuration. The included 2,000 GPH submersible pump ensures consistent, high-volume water circulation throughout the full system. All plumbing and installation components are included. Freshwater builds receive a sliding glass cover for both the display tank and sump.

The all-black aluminum frame is engineered to resist corrosion, tension deformation, and torque stress under the continuous load of a fully operational 400-gallon system,  built to remain structurally sound and fade-free for years of continuous use. The sleek black finish creates a dramatic visual contrast that makes every fish, coral, and aquascape element stand out.

Compatible with saltwater reef, FOWLR, freshwater biotope, and planted aquascape configurations.
