Tetra Bio-Active Pressure Filters are the perfect thing for those looking to take care of very sensitive fish through optimal mechanical and biological filtration in water garden ponds. Tetra Bio-Active Pressure Filters come in three sizes: Model 1500 – For a maximum pond size of 1500 gallon, has a maximum flow rate of 750 gallon per hour. Model 2500 – For a maximum pond size of 2500 gallon, has a maximum flow rate of 1250 gallon per hour. Model 4000 – For a maximum pond size of 4000 gallon, has a maximum flow rate of 2000 gallon per hour. Bio-Active Pressure Filters made by Tetra have a small advantage over common mechanical or ordinary biological filters and that advantage is summed up in one word, pressure. With a pressure filter, it is possible to pump larger quantities of pond water into a smaller space, and clean out more efficiently with a special backwash cycle that breaks up that evil build up of crud that makes a good pump useless. Tetra pressure filters have two main stages of filtration; the first involves a mechanical filter for larger debris in the form of sponges (the water is forced through at high pressure).The second stage involves bio-rings, of material that an provide excellent environment for beneficial aerobic bacteria that cut down on microscopic wastes on an invisible level, ensuring that your pond keeps that water crystal clear. Dimensions: 1500 – 15” Diameter x 16.5”H, 2500 – 15” Diameter x 20”H, 4000 – 15” Diameter x 23”H. Intake/Discharge: 1-1/4" - 1-1/2" Step-down Barbed Connectors
