The airstar pumps put out too much air for the medium body
the airstar 1500 is doing 1500L/hr of air with a needlewheel
the airstar 2000 is doing 2700L/hr of air with a threadwheel
Also i liked the quietness of the eheim pumps
Once you fire up your skimmer you will see it produces a lot of foam these skimmers do not need that much air
