Review on Enhance Filtration Efficiency with Marineland Bonded Filter Sleeve for Magnum 350 Canister Filter by Jackie Morales

This Magnum 350 size filter sleeve is perfect for both of my fountain pumps. I needed a filter that would fully cover my pumps to keep them clean and free of garden debris. While not exactly the right application, these sleeves work great. My fountain pumps are approximately 4 inches long, 3 inches wide, and 3 inches high. I sewed one end of the sleeve. Orientation of the water inlet hose. I slipped the filter sleeve over the base of the 4" x 3" pump and lined it up like a tube sock. The hose and power cord exit freely from the top open end of the filter. The pumps do not form slimy deposits and work without interruption. The quality of the filter is excellent.
