Filter Socks are used on overflows to remove small floating particles from aquarium water. This can dramatically improve water quality and reduce maintenance on filters that would otherwise become clogged. Filter socks come in mesh or felt and with a plastic ring or draw string. Bulk Reef Supply recommends starting with felt socks and switching to mesh if they clog faster than desired. Bulkreefsuppl.com also carries filter sock holders from Vertex and CPR Aquatics.

Find the filter sock that works best:

Mesh: Thin, doesn't clog as easily as felt

Felt: Thicker, better at removing particles, but can clog faster

Plastic Ring: attaches via ring that fits common sump holders

Draw String: attaches directly to plumbing
