ABSTRACT:
A skimmer basket weight is provided, which is made of a heavy material having a density greater than 1.0 g/cm3, coated with a water proof coating, and is configured to have a circular outer periphery with a hollow opening for allowing water flowing through. The circular outer periphery has a diameter substantially matching an inner diameter of a bottom of a skimmer basket. When in use, one places the skimmer basket weight inside the skimmer basket, and affixes the skimmer basket weight on top of the bottom of the skimmer basket. The weight prevents the skimmer basket from floating and tipping over inside the skimmer well. Also disclosed is a skimmer basket assembly which includes a skimmer basket, the weight and a fastening means.
