Large-Scale Pond Filtration with Advanced Automated Cleaning The Oase BioTec Screenmatic² 39000 handles ponds up to 39,000 gallons with gravity-fed filtration that combines biological and mechanical cleaning. This premium flow-through filter maintains crystal-clear, healthy pond water without requiring pumps to return water to your pond. Enhanced Self-Cleaning Technology Features an adjustable intelligent cleaning sensor mounted above the screen that monitors debris build-up and automatically empties the screen into the collection tray when needed. The double-sealed screen motor and reinforced screen materials deliver extended service life for large pond applications. Professional Three-Stage Biological Filtration Includes 18 filter foams in three different densities (4 blue, 7 purple, 7 red) plus 12 phossless filters, creating optimal environments for beneficial bacteria that eliminate ammonia and nitrites. The foams clean directly inside the filter using pond water, preserving crucial bacteria colonies while minimizing water waste.
