You are purchasing a high quality, UK manufactured filter sock, made from high quality Nylon. We are recommending these for use in ponds, as a mechanical filter, but they can also be used in many other applications, such as holding filter media in pond filters, and collecting waste from a pond vacuum. This pond filter bag is made from extremely durable nylon, and can simply be rinsed and reused many times, by turning inside out and spraying with a hose. These filter socks will last being cleaned hundreds of times. These filter bags provide crystal clear water! They will remove particles up to 400 microns - 0.4mm. It is surprising to see how much waste these bags remove from your pond! These bags contain a drawstring, allowing you to tighten the bag around a pipe. We sell pond filter bags in both 400 micron and 800 micron ratings, in 2 different sizes.
