Those are the exact same problems the Sicce pump has! I haven't heard of other people having this trouble with the Atman, maybe you just got a bogus pump from the get go? I have had a 120 Cone (on nano) with the smaller Atman 1100 pump on it for about 6 months, and I haven't had any restart issues with it at all. Actually no complaints at all about the skimmer, which is why I want a bigger one for my reef.
FWIW, in my research I have been hearing if a person puts the AquaMaxx Large Red Devil Needle Wheel on the Sicce 2500 pump that it restarts with no issues. I'm going to continue this research, and it if is consistent then I will just buy the SWC 180 Cone.
