I run the pump in a 112L Wels pool with mobile HMF reactor and a 25er airlift. The air power that emanates from the pump outstanding! Flow and air supply in the basin perfect for my little ones. This is unfortunately the only positive thing I can date report on the pump. As my catfish need high air flow and little, the pump has to run at full power.
Since we are talking about the problem of volume !! The fact is really very very noisy when properly air through needs.
Why do people here so I can write from extremely low just do not understand, unless you have a Sprudelstein off and throttle the power up to a minimum, since it is then barely audible.
The basin runs luckily in the next room, but the roar is still very annoying if you are staying in the area and is working on the Basin. In another review one reads that one should not use diaphragm pumps with air lifters in the bedroom, which is utter bullshit !! I run in the bedroom 2 large 450L pool and some Nanos and running all over airlift with 2 Hailea pumps V series. These pumps can not throttle you and which are not to hear even though they are anywhere in the room and only on a small foam board.
As for the durability of this pump here of course I can not say that is the time to show then, but a whisper is really something else!
