counting

My power went off early Sunday morning. Have been cycling my canister filters and AC filters on 3 times each day for about 20 minutes and my sponges the same using a battery pack. So far everything seems ok, but I feel the need to feed the fish. How long I'd the maximum I can go with out feeding?

I have been up for 17 hours straight so far. Lets see if I can make it 24. :eek:
