Hi all, we have a scheduled power outage of 8 hours coming up. My whole house is electric. Ambient temperature is around 12-14degrees down here in Vic. I will be using a computer UPS to maintain some water circulation and filtration (should last for 8hours) Any Ideas how to keep the water warm during this time? I am thinking preheat the room, heating a smaller tank to a "higher temp" and doing a live stock transfer after few hours if my main tank temperature drops......short of a power generator any further ideas?
