Aquatic Experts Felt Filter Socks – 7 Inch Ring Style, 200 Micron for Sumps & Aquariums (2 Pack)

Overview

Crafted by Aquatic Experts, these Felt Filter Socks are designed to fit standard filter cups with a smooth molded ring. The 7-inch size and 200-micron felt create a reliable mechanical filtration stage for sumps and glass tanks alike. They’re not compatible with Red Sea filter trays, so pairing them with compatible cups ensures a snug, secure fit and steady performance through routine maintenance.

Key benefits

• Ring-style design for easy installation in standard filter cups, delivering consistent filtration without complicated setup.
• 200-micron felt provides dense mechanical filtration, capturing fine particles such as uneaten food, fish waste, detritus, and debris.
• Durable, reusable construction—dense polyester felt holds its shape through multiple cleanings, offering a long-lasting media option.
• Improves water clarity by trapping suspended particles before they break down, helping maintain a cleaner appearance in both freshwater and saltwater tanks.
• Easy maintenance: clean and reuse the socks to support steady sump performance and reliable filtration over time.

What you get and how to use

Each pack includes two 7-inch felt filter socks that slide into standard filter holders. They’re ideal for hobbyists and professionals who service multiple tanks or sump setups, providing a straightforward filtration upgrade that doesn’t require complicated replacements.

• Place the ring around the top edge of the sock to ensure a secure seal inside the filter cup.
• Rinse after use to remove trapped particles; repeat as needed to maintain filtration efficiency.

Care and compatibility

Durable by design, these socks resist deformation through repeated cleanings, preserving filtration performance project after project. For best results, pair with compatible filter cups and routinely inspect for wear. Note the socks are not suitable for Red Sea filter trays, so check your sump setup before purchase.
