The OASE BIOsys IP-200 pond skimmer (in pond) has a unique design that allows the skimmer to be located in the pond and makes it an excellent choice for retro-fitting an existing pond.  The skimmer base is anchored by small stones, while the skimmer itself naturally adjusts to varying water levels up to 5 inches. Keeps pumps from clogging by pulling water and debris from the surface before they settle.

The OSASE BIOsys OP-300 pond skimmer (out of pond) skims floating debris from the surface of the pond. Pond water enters the skimmer unit via a 7 in. wide weir and is then filtered through a filter basket. The BIOsys Skimmer draws debris from the surface of your pond where it can easily be removed. A unique flap behind skimmer opening draws water only from the extreme surface, speeding up surface movement and reducing possibility of fish entering the unit.
