So irene has knocked my power out here on long island and doesn't look like it will be fixed until friday. Luckily i do have a generator and i have been able to keep the fish tank running for most of the day but at night the generator just gets to hot and has to be shut down.The tank has been without power from 11:00 pm until 7:00 am and still so far i have no losses. I am curious if what i am doing is all i can do to help my fish survive the week. I keep the Lid open and basically wake up every 3 hours to stir the fish tank (i know it really sucks) do i have to be doing this? or is keeping the Lid open working as far as providing oxygen.
