BZA Congo – 22L Stainless Steel Canister Filter
Dual Inlet Configuration

Introduction

The BZA Congo is a 22-liter stainless steel canister filter built for large aquariums that demand extreme flow, high media capacity, and long service intervals. Designed for heavily stocked systems, predator tanks, and large aquascapes, the Congo delivers massive turnover while maintaining precise control through its DC pump system.

This dual inlet configuration is powered by a 55W DC pump rated at 7200 L/h, providing aggressive but controllable circulation across large aquariums. Dual inlets improve debris collection from multiple zones, increasing mechanical efficiency and reducing dead spots within the system.

The Congo uses a fully open internal media chamber supported by stainless steel grates instead of restrictive trays. This allows unrestricted flow, larger media capacity, and consistent biological performance over time.

The system operates nearly silently during normal use.

Filtration Design

The Congo uses a wide-open internal layout designed for maximum flow and long-term biological stability.

Included Internal Media Layout from bottom to top
• Coarse foam filter pad for mechanical filtration
• High-capacity biological media zone
• Open upward flow path to outlet

The absence of trays prevents restriction and allows media to remain oxygen-rich and unclogged, improving efficiency and extending service intervals.

What’s in a Name

The Congo River is one of the most powerful river systems in the world, known for its immense flow, depth, and biodiversity. Its strength and scale inspired the design of this high-capacity filtration system.
