Available in 20 cm / 25 cm / 37 cm

The Honeycomb Filter Sock (4-inch diameter) is a premium filtration accessory designed to enhance water clarity in aquariums, sumps, and overflow systems. With its advanced 3D honeycomb weave, it captures floating particles and detritus while remaining easy to maintain.

Key Features

• Three size options: 20 cm, 25 cm, 37 cm — choose based on your filter sock holder or sump depth.
• 3D honeycomb structure: Efficiently traps suspended debris in all directions, increasing contact area and filter efficiency.
• Easy maintenance: Slides in and out effortlessly for quick replacement or cleaning.
• Durable material: Woven synthetic fabric resists deformation and lasts through many clean cycles.
• Improved water clarity: Helps prevent fine waste from returning to your tank, supporting better overall water quality.

Uses & Application

• Install in sump or overflow filter sock holders where a 4-inch sock is required
• Filter out particulate waste, detritus, uneaten food and debris
• Ideal for both freshwater and marine setups
• Use in cascade filter sock holders, multi-sock racks, or custom filtration stations

Usage & Maintenance Tips

• Measure the depth of your sock holder or housing before selecting length (20, 25, 37 cm).
• Install with the open end upward to allow debris to collect downwards.
• To clean, remove the sock and turn inside out, then rinse or spray thoroughly to dislodge trapped particles.
• Avoid harsh chemicals or bleach when cleaning; use gentle rinses in aquarium or RO/DI water.
• Replace when fabric’s pores appear clogged beyond cleaning or if fabric frays.
