JB, regarding your question "Have you tried running just the pump with out the blowers?" We've played around a bit with different combinations of the 3 items (well, and each of the 2 ice eaters) turned on/off while we're away from the property. Each of them on their own aren't able to keep much of a hole open. We started out with the 2 ice eaters before we put in the well, and they wouldn't do it. The well doesn't do it on it's own either, but, I think it's more of a distribution/circulation issue, and either the ice eaters, or something like the plumbing set up that fowlplay has, is probably critical. So, right now, we're just running one ice eater 24x7 that keeps a bit of a whole open, and then when we show up we turn on the well and the other ice eater, and it opens up a nice hole, usually over-nite. Of course, actual mileage varies, as many others have reported much better luck with just ice-eaters than we had. But, the well has absolutely made a huge difference for our set up.
