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.
Most pondkeepers know that the best way to ensure clear pond water is with an ultraviolet sterilizer. Some often overlooked factors are what to do when the UV light is not doing the job anymore. Usually, this is a simple as an old lamp. Depending on the brand, UV lamps should generally be replaced about every 12-15 months of use.
