A good helper for swimming pool cleaning: The skimmer pool can filter leaves, grass, hair, oil, pine needles, pollen, insects and other residues that block the swimming pool filter system. Protect the pool filter system: The skimmer can help protect the pump impeller and shaft seal from damage or blockage, and extend the service life of the pool filter/filter system. General purpose: pool skimmer socks are suitable for almost all types of pool skimmer basketsHigh-quality materials: The skimmer net is made of high-quality nylon cloth, which is elastic and easy to stretch, enough to cover the skimmer basket, suitable for use in swimming pools. Note: Replace or clean the pool skimming net every 4-6 weeks. The best option for you is to check the skimmer basket socks every week; if too much is wasted, they will overflow and dirty the pool. Please do not use this product while dissolving chlorine tablets in the basket. Otherwise, the socks of the swimming pool skimmer will be corroded.
