SPECSTAR Pressurized Biological Pond Filter with 13-watt Lamp — 6000 L/H (1580 GPH) for Koi Ponds up to 800 Gallons or Ornamental Ponds up to 1600 Gallons

Durable ABS construction: Built from reinforced ABS material with good insulation properties, this pressurized pond filter resists sunlight, water exposure, and aging. Three adapter sizes (3/4", 1" and 1¼") are included to fit a variety of pipe connections. Effective mechanical and biological filtration: Four internal filter sponges trap suspended particles, sediments and some organic matter, while the built-in 13W lamp helps reduce water-borne pollution. High flow capacity for medium ponds: The unit delivers a maximum flow-through of 6000 L/H (1580 GPH), making it suitable for ornamental ponds up to 1600 Gallons or fish/koi ponds up to 800 Gallons. Easy installation and operation: The filter is simple to set up and put into service quickly. A switch lets you change the outlet function between filtered-water output and sewage/discharge. Low-maintenance design: A crank handle on top operates an internal cleaning rod so you can flush the filter without opening the housing. Both the sponges and the lamp are replaceable for continued performance.
