Socks capture and remove the smallest debris like leaves, grass, oil, hair and other floating debris before it reaches and clogs your pool pump and filters, so your filtering system will need less servicing. When socks are soiled, they can be washed out and reused several-time before being replaced. Be careful not to dissolve chlorine tablets in your sock or basket, as they can erode the sock.
