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.
