SUNSUN 400B / 500B / 600B Stream Tank

All-in-One Tabletop Aquarium | Side Filtration | Tri-Colour Spotlight

Bring the relaxing look of a natural stream into your home or workspace with the SUNSUN B Series Stream Tank. Designed with a clean, modern profile, this all-in-one aquarium combines a clear glass tank, integrated side filtration system and adjustable spotlight into one compact setup.

Available in 400B, 500B and 600B, the series suits everything from smaller tabletop displays to larger planted aquascapes. Its integrated filtration draws water from different levels of the aquarium to help collect surface film, suspended particles and debris while maintaining continuous water circulation.

Natural Stream-Style Water Flow

The specially designed duckbill water outlet creates a broad, gentle flow that helps simulate the movement of a natural stream. Continuous circulation also improves surface agitation and oxygen exchange, creating a more dynamic aquatic environment for fish and plants.

Multi-Level Side Filtration

The built-in side filtration system keeps filtration equipment neatly contained at the side of the aquarium for a cleaner overall appearance.

The multi-level intake design helps target different types of waste:

• Upper intake helps remove floating food residue and surface oil film
• Lower intake helps capture suspended particles and debris
• Continuous circulation helps move waste towards the filtration chamber

Multi-Layer Filter Chamber

The spacious side filtration compartment allows water to pass through filtration media layer by layer, helping remove impurities and maintain clearer aquarium water. The integrated design also eliminates the need for a bulky external filter hanging around the tank.

Adjustable Tri-Colour Spotlight

Create different moods for your aquascape with the included MS-301RBW spotlight. Choose between Warm White, Warm Yellow and White Light to complement your fish, plants and surrounding interior.

The compact gooseneck design keeps the aquarium looking minimalist while directing illumination exactly where you want it.

Clean, Modern Tabletop Design

With its streamlined rectangular profile and integrated filtration, the SUNSUN Stream Tank fits naturally into modern interiors. Depending on the size selected, it works well for living rooms, offices, desktops, cabinets, entryways and other indoor spaces.
