Waterbox 7" Filter Sock Silencer

Reduce noise and improve water flow with this custom-designed 7" Filter Sock Silencer, made specifically for Waterbox filter sock systems.

This silencer is designed to sit neatly on top of a standard 7" filter sock and helps break and distribute incoming water evenly before it enters the sock. By doing so, it significantly reduces splashing, gurgling, and waterfall noise that often occurs in sump systems—especially at higher flow rates.

Compatible Waterbox Systems

This silencer is confirmed to fit the following Waterbox aquarium systems that use 7" filter socks:

• FRAG 145.5
• FRAG 165.6
• REEF 180.5
• REEF 220.6
• REEF LX 240.5
• REEF LX 290.6
• REEF LX 340.7
• INFINIA 165.4
• INFINIA 215.5
• INFINIA 275.6

Benefits

• Significantly reduces sump noise in high-flow systems
• Helps maintain consistent filtration by distributing flow evenly
• Ideal for display tanks in living spaces where silence matters

A simple yet effective upgrade for reef keepers who want a quieter, cleaner, and more refined sump experience—without compromising flow or filtration performance.
