I live in nj apparently we are gonna get pounded by the hurricane. I can't afford a generator so I would like to know what to do if the power goes out for an extended period of time? I've been to 3 stores today looking for battery powered air stones and couldn't find any. How long can fish last without filtration? As far temperature I believe the tanks will drop to about 72-73 without heating. Will the bio bacteria die off without filtration? I own various cichlids, plecos, catfish, loaches.
