HaileaLuftpumpe Aco 9610 10Watt, 10l/m, max. Druck 1,5m

very good and strong pump with the ability to set the power, it works really well on all stones, Is the same power. Earlier pumps, after connecting, limited the work of one stone at the expense of other one. There is no problem with that. It's great for aeration and oxygen tests always come out of the highest quality
