The Oase BioTec ScreenMatic Large Pond Filters are flow-through biomechanical gravity filters with multi-stage filters in a compact package, perfect for large ponds with high fish load. Mechanical filtration separates out particles and debris using a 300-micron mesh screen, which is cleaned automatically by the filter every 15 minutes! This advanced, innovative filter offers multiple innovative features such as automatic debris separation, double-sealed motor, large sludge basket, and optimized water level control.
3 Stage Filtration:
Mechanical stage: Water flows through debris screen, which deposits debris into separate tray for easy removal
Biological stage: Water passes through a foam filter zone that promotes colonization of beneficial bacteria
Final stage: "Phosless" cartridges bind phosphorous and remove it from the water column, inhibiting algae growth
Boasts an amazing filtration capacity relative to its size, with large sludge basket
Automatic debris separation using self-cleaning screen is partially self-maintaining
Intelligent cleaning sensors detect debris and activate the screen
Water distributors ensure ideal water flow without clogging
Double-sealed motor for long life
Optimized water level control
