It is common to use pond netting to repel fish-eating predators (such as herons or cranes) and to keep ponds free of leaves and debris. This tightly woven 1/8" mesh pond cover prevents small debris from reaching the water. This netting is resistant to tears, mold and mildew.
UV treated for longer life -- up to 16 years!
Available in sized from 6' x 10' to 20' x 30'
It is also possible to use a large beach ball or other floating object to create a tenting affect to further aid leaves blowing off of the cover instead of collecting on the cover.
