CO2 tank ran out - can't get to LFS
I have a high tech extremely dense-planted tank that runs CO2. Unfortunately my tank just ran out and a massive snow storm smacked the Pacific Northwest and I can't get out of my driveway. It's going to take a couple days for me to get the tank refilled, so I was wondering what I should do in the meantime? Should I just keep my light cycle the same and dose gloc? Or would this be the time to do a blackout until I can get it refilled? The tank just got established and was beginning to grow into the scape I want, and I don't want to crash it. This tank has a Ray II over it and you can't see the substrate with all of the plant mass.
Thanks a lot!
