The Pond Sieve is a simple to use and effective mechanical pre-filter for pressurised filtration systems and surface skimmers. It is essential to use the Pond Sieve in front of any type of pressurised bead filter to help prevent the necessity of excessive backwashing or clogging of these types of biological filters. The Sieve is simply connected to either the bottom drain line or a skimmer line and is set 50mm above the surface of the pond. The Pond Sieve utilises a 300 micron screen and the flow is regulated by a new floating weir system which overcomes the reliabillity and installation problems often associated with this type of product in the past.
