The Anti-Electrolysis Basket Weight Zinc Anode was designed to stop metal erosion and plaster discoloration due to galvanic corrosion. It also keeps skimmer basket in place. The weight bolts permanently inside or outside any skimmer basket.
The Zinc Anode will sacrifice itself and corrode before all other metals in the pool. In doing so, the anode protects other metal parts from galvanic corrosion.
