Fish Fanatic
We've got a power cut here (i'm running a laptop from a UPS so i can still get online). My fish are ok cos i've got the pumps hooked up to the ups as well, but my girlfriends tank at home doesn't have any other power source. As she's running under gravel filters, how long will it be before not having power to the air pumps start causing problems with the water? Thanks
