Got a generator , big enough to run the furnace , fridge , and some lights/outlets , but not all at once . Saved my tail after Sandy , when we were out for 9 days . However , my fish are in the basement , which went dark and stayed that way . No air,lights,filters . Fed ' em once after about 4 days , mostly because I felt guilty . No losses . I travel some so I know from experience that my tanks can be safely ignored for a week or 2 with no problems .
