Im in UK. My local Asda and Tesco Superstores are 24/7 (well not on Sundays). Also have a local 24/7 Turkish supermarket down the road. But I am in London..
Certainly was a traumatic time. Wen to bed at 4 a.m with a pounding head ache most probably from stress and was up at 7 a.m for work!
4 days since and all fish doing great.
I have a generator but you need to be there to start it etc. I now have a low wattage reef tank circulation pump that has auto battery back up and battery is always on charge, it can run for 24 hrs. I am thinking of doing the same with a sump circulation pump too, not cheap but it saves a lot of worry.
