I have a huge pond with no filter, with stream.
In the spring I had masses of algae clouds in pond.
this belueftungspumpe is quieter than any which I in my many years as an aquarium, pond owners -and ever had.
belueftungskugeln by the four is the pond supplies along its entire length with oxygen. even the lowest point in almost 2 meters is well ventilated.
individual adjustment makes it easier to optimize.
the algae have disappeared in a short time up to normal levels. even on hot days remains the pond clear.
the pump is in continuous use, connected to a timer, which turns off at night.
it works flawlessly.
because they must not be exposed to the weather it was adequately protected, allowing external commissioning.
a top quality product which has its price more than worth it.
