Everything was ok. My power was out for about 24 hours.
I have little screw type control valves in my co2 lines from the bottle to the tank. I ended up just closing them mostly off, and unscrewing the cap slightly to let some of the co2 escape so that the bottles didn't explode.
My plants grew about 2 inches in the dark. crazy style. But my fish are ok. They were a bit chilly when the power finally kicked back on tho.
The water level in my tank went down a lot too. i let it run low overnight to offgas anything that might be high in the tank, then set the water back to the top, and turned the co2 back on.
EDIT: oh, and thank you for checking in and replying, travis.
