True Products Galvanised Metal Christmas Tree Netting Funnel. Comes complete with a rubber brake ring and can be used either freestanding or remove the legs to fasten to a table top. The legs incorporate a handy netting cutter. Used by growers and retailers to wrap trees securely for transportation and prevent damage to branches. Not only used for Christmas Trees but for all trees the year round. Also for filling barley straw into netting for use as an algae remover for lakes. A sleeve of netting filled with barley straw is the perfect way of controlling blanketweed and ensuring crystal clear pond water. Not only is it effective, it's also completely natural. Barley straw naturally disrupts the development of each algae bloom and will destabilise blanket weed, so it can be removed through your pond filter. Barley straw works by breaking down in pond water, producing a variety of chemicals that prevents the growth of algae. While these chemicals don't kill algae they send signals to the algae that tell it to stop growing, this is why barley staw is often called 'algae control' and not 'algae treatment' or 'algaecide'.
