I recently purchased a used hot tub that was winterized. The previous owner put prestone in the tub as an extra precautionary measure as we're up in Ontario Canada where temperatures can dip well below freezing. I am looking for some advice on how to get this hot tub up and running. Would I fill the tub up a third or half way and drain it to get rid of whatever prestone is in the pipes? I am new to hut tubs so I don't really know a whole lot about how to do this the best way.
Is it ok to fill the tub right now with the temperature around 0 celsius (32 fahrenheit)? Possibly even a few degrees cooler?
Thanks,
Matt
