Tetra PRF 4000

The TetraPond ClearChoice Pressure Filters force water through sponges and then through bio rings to help maintain clear and healthy pond water. Its biological filtration converts harmful ammonia into relatively harmless nitrates. It is designed with an easy, one step back flush valve for cleaning sponges and bio media. You can also bury to conceal and don't have to worry about a leak due to its robust latches and O ring seal.Each pressure filter is sold as either a stand alone unit or with an integrated UV clarifier to provide permanent control of suspended algae and reduce green water. If you later decide you want to add a UV clarifier to your pressure filter TetraPond also provides UV upgrade kits.
