My 1100 starts every time. I have it on a timer to shut off once a day for feeding, and I occasionally stop/restart it to clean it. Has never had a problem. I think some of the restart issue was early units, and people running them on wavemakers even though the manufacturer says not to. I have talked with some people in the club and no one that I talked to had the restart problem.
Also, the controller doesn't shut off the pump like a wavemaker, it just slows the speed down to 30%.
And I think some of the reported problems with the Seios is from people who are still very upset over having tank wipeouts from the Rio powerheads that contained oil a long time ago, and are just out to trash Taam.
Anyone find a price on these yet?
