This is a genuine ASM Sedra replacement needlewheel impeller, specifically designed to restore or enhance the performance of your protein skimmer. The needlewheel design is a critical component responsible for generating the fine, dense micro-bubbles necessary for efficient waste removal and maintaining pristine water quality in your saltwater reef aquarium.

This replacement impeller is engineered to precisely fit several popular Sedra pump models, including the Sedra 15000, G-4XX, and G-6X. Utilizing an OEM replacement ensures optimal compatibility and the consistent performance you expect from your protein skimmer, helping to effectively pull organic waste from your tank's water column.

This product is ideal for reef aquarists who own protein skimmers powered by the specified Sedra pumps and are experiencing reduced skimming performance due to wear or damage to their existing impeller. Replacing this vital part can significantly improve your skimmer's efficiency, ensuring a healthier and more stable environment for your corals and fish.
