Good to hear your fish stuck it out. Like steveothery said, a generator would come in handy for times and situations like those. Battery operated airpumps will go along way also, if you don't already have any.
Yeh i'm pleased! Any idea how long this situation is dangerous without any filter? Ie did alot of bacteria die in my filter do you think? Everyone looks fine in the tank just now its been back on for a few hours.
If you lose beneficial bacteria, your tank will go into a mini-cycle. I test the water for ammonia after a power outage and will do water changes if there is any ammonia present. I closely monitor the water parameters for a few days to make sure the mini-cycle is over.
