Premium Quality Schedule 40 Aeration Tube - Aquarium Air Bubble Oxygen Diffuser for Fish Tank, Koi Pond, and Hydroponics - Promotes Health of Fish and Plants (0.39" ID, 0.63" OD, 0.12" Wall, 6.56FT)

• -This is an extremely porous drainage hose（Schedule 40 - 0.39" ID, 0.63" OD, 0.12" Wall, 6.56' Length）, specially designed for aquaculture.Enhances Water Quality ,Ventilate like the professionals in fish farming and aquaculture.
• -The hose is made of premium materials and sinks to the bottom of the pond when combined with a steel housing. Thanks to the round construction of the hose, it is ideal for aerating the filter chamber and for use in floating and fluidized bed reactors.
• -Low internal resistance for excellent diffusivity, robust and durable, easy to clean, unclogs and does not wear out, guaranteed to maintain a constant excellent flow rate.
• -Japanese breeders use the aerator ring for their Koi pond as it prevents dangerous oxygen depletion both in summer and winter. It is also suitable for spiral chambers and moving bed systems to achieve the best possible movement.
• -A high oxygen content in the pond water is a prerequisite for the health of Koi and other pond inhabitants. Sufficient oxygen is also required in the water to trigger the biological decomposition processes of ammonium into nitrite and nitrite into nitrate. To avoid oxygen depletion, you need to equip this ventilation hose.

Product Description: For the microbiological processes that take place in the pond and filter, oxygen is continuously required and consumed. The result of this original Japanese ventilation hose is a very fine pearly outflow, which is required for a good oxygen supply in the water. Another advantage of these special ventilation hoses are the low counter pressures that the ventilation pumps only need to apply a little when operating with these hoses. These ventilation hoses were specially made for fumigation. Important: This orig. Japanese ventilation hose cannot be compared with a drip or soaking hose! Use: For a good air supply to these ventilation hoses, we recommend using connections with a diameter of at least Ø16 mm or, better, Ø19 mm. To ensure a sufficiently large supply line so that unnecessary back pressures are avoided. You should expect approx. 15-20 liters of effective air consumption per minute per meter of ventilation hose. Over 20 liters of air / min. is also possible at any time with these hoses. Less than 15 liters of air / min. shouldn't be, this is the minimum amount that should be blown in to get an even air distribution. The longer the ventilation hose, the more air is required. So that a lot of air does not flow out in the front part and little at the end, the air supply should always take place from two sides if possible, e.g. by installing a T-piece. As shown in the example above.
