Abstract
A skimmer guard has first and second brackets configured to bear against opposite walls of a skimmer passageway, and a plurality of resiliently deflectable ribs extending between the first and second brackets for blocking objects from passing into the skimmer. The ribs are configured and dimensioned to bias the first and second brackets against the second wall of the skimmer passageway to hold guard in a fixed position.
