Talk about being scared, im in NY and the weather really hit the fan here, lost power from yesterday afternoo around 3:00pm until 4:30 or so today, seven tanks, all ofcourse overstocked, with no fitration for over 24 hours. I had battery powered air an all of them but was still more than a little concearned, Came home after work and everyone is still fine, heavy water changes and seems to be no ill affects, thank the gods. just wanted to share with ya all.
