Benefits of the MicroSkim™ This scaled down version of professional models skims the leaves and debris from the surface of the pond into an easy to clean debris net. * Debris net and filter brushes act as a prefilter for the pump, preventing leaves and debris from clogging it. Reduces maintenance associated with placing pumps on the pond bottom. * Requires 2-3 minutes every other week to clean while standing outside the pond. * Can easily skim ponds up to 150 sq.ft. * Handles pumps from 500 gallons per hour up to 2000 gallons per hour. * Excellent prefilter for a biological filter, such as the MicroFalls™, where maximum dissolved oxygen levels are required. * Hides pump and plumbing from view. * Built in overflow to handle heavy rainfall. * Easily attaches and seals to EPDM Fish-Safe liner. * Made from tough, roto-molded, high density polyethylene plastic.
