Just a FYI, mine quit working right after I mixed a bunch of alcohol in the water to keep it from freezing. It did work for a short time as I was increasing the mixture of alcohol. It didn't freeze at zero but you could tell the thing didn't make as many bubbles. the temps have been around 15 above to 10 below for a while now. It's a hassle to mess with the water freezing. One of the warmer days I did clear out the alcohol and reintroduce water, that's when I found it to not work at all. Everything appeared to be powered. I have given up on the unit until it warms up outside. hopefully it will be warming in a few weeks. I plan on cleaning the unit with CLR. maybe that with get it working again. I also need to get a amp meter.
