The Pond Guy AllClear G2 Bio Pressure Filter & Ultraviolet Light Clarifier with Backflush System, Pressurized External UVC Biological & Mechanical Filtration, Koi Fish Water Garden, All Clear 3500

AllClear filters have high output, low energy 9-watt UV clarifier. The ultraviolet clarifiers expose pond water to a high output ultraviolet light to clear the water before it travels to the chamber. There is an indicator light on the lid to let you know it's working. Inside the chamber, alternating low- and high-density filter media pads (similar to a sponge or foam) filter out dirt, organic mess, dead green algae, and debris particles big and small. The large filter media pads also provide a place for beneficial organic bacteria to grow. The good bacteria break down ammonia and nitrates that can diminish water quality and harm aquatic life such as koi, fish, minnows, tetras, goldfish, ducks, frogs, and turtles. This multistage mechanical and biological filtration process polishes the water before returning it to your backyard pond. Restores cloudy, murky pond water to a crystal clear blue appearance. With a commitment to simple and easy maintenance, an internal diverter valve and waste outlet was added. When a cleanout is needed, remove the backflush control cap, and turn dial from "filter" to "clean." Lift the handle to compress the filter media inside the cannister. Then slowly pump the handle to force out debris. Repeat pumping cycle. Ideal for water gardens and koi ponds. In addition to ponds, the AllClear Pressurized Filter is a great solution for an aquarium, fish or minnow tank, indoor fish or turtle pond, aquagarden, and many aquaponics applications. You can bury the base container in the ground and camouflage with a fake rock cover, ensuring your small pond filtration system is hidden and blends with your outdoor landscape. Fake rocks protect your equipment from the weather and the sun. Please refer to the products gph flow rate to ensure the correct pond and pipe / tubing size setup. Various sizes available depending on how many gallons are in your pond. Pair with a properly sized pump. You can connect to a waterfall if you do not exceed max flow rate.
