Designed by Aquarists for Aquarists
The AF OceanGuard 435 goes beyond aesthetics. Its design incorporates practical solutions developed around the needs of experienced reef keepers.
The filtration, plumbing, overflow and sump have been carefully designed to support efficient operation and easier aquarium maintenance.
Efficient Filtration
Adequately sized pipe diameters help provide efficient water movement through the filtration system.
Precision Water-Level Control
A quality gate valve allows precise adjustment of water levels, helping optimise the overflow and minimise unnecessary water-flow noise.
Smart Sump Design
The sump incorporates intelligently designed cascading chambers to support the filtration process while helping reduce water-flow noise.
Easy Maintenance
The removable weir comb makes cleaning the overflow easier and helps simplify routine maintenance.
Blackout Protection
A built-in check valve helps prevent water from flowing into the sump during a power outage, providing additional protection for your aquarium system.
Ultra-Quiet Operation
The AF OceanGuard 435 has been engineered to provide a quieter reefing experience.
Multiple design elements work together to reduce vibration and water-flow noise, including:
- Anti-vibration foam beneath the display and sump
- Self-leveling downflow
- Noise-cancelling overflow cover
- Smartly designed sump chambers
- Precision water-level adjustment
- Gate valve for flow and noise control
The overflow's removable weir comb and specially designed silencing cover help make water movement almost inaudible, allowing you to enjoy your aquarium without excessive background noise.
Elegant Rimless Design
The rimless construction creates a clean and contemporary aesthetic while maximising the viewing experience.
Combined with Optiwhite™ glass, black silicone and black overflow, rear and bottom glass, the AF OceanGuard 435 provides a sophisticated display that allows your corals, fish and aquascape to take centre stage.

Exceptional Viewing Clarity

The AF OceanGuard 435 has been designed specifically around marine aquarium requirements, incorporating suitable glass, silicone, plumbing, overflow and filtration solutions.
Quiet & Comfortable
Anti-vibration materials, a self-leveling downflow, noise-cancelling overflow and precision flow control combine to minimise unwanted operating noise.
Built for Long-Term Use
High-quality waterproof materials, durable connections and robust cabinet construction are designed to provide a dependable foundation for a long-term reef system.
Easy to Maintain
The removable overflow comb and intelligently designed sump chambers make routine cleaning and filtration maintenance more convenient.
Protection During Power Outages
The integrated check valve helps prevent unwanted water flow into the sump during a blackout, adding an extra level of system protection.
Filtration & Plumbing
Efficient filtration is an important part of successful reef keeping. The AF OceanGuard 435 uses appropriately sized pipe diameters to support efficient water movement through the filtration system.
A quality gate valve provides precise control of the water level, helping you fine-tune the overflow and minimise water-flow noise.
The sump's cascading chamber design further supports the filtration process while helping manage water movement and reduce noise.
Blackout Protection
Unexpected power outages can cause water to move back toward the sump. The AF OceanGuard 435 incorporates a check valve designed to help prevent water from flowing into the sump during a blackout.
This additional protection helps give reef keepers greater peace of mind during unexpected interruptions.
