Fleece Rollers, Power Filters, Socks, and Pads

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.
