If you did one last night, you should be fine. Oh, feed your fish too. I didn't feed mine during the blackout because I didn't want to expose the tank to any light. Do a WC after.
Now get black garbage bags or towels, blankets...whatever works and tape up your tank for at least 3 days. No peeking! This method worked to a degree for me, but I had it taped up for 5 days.
I ended up getting a used Magnum 350 with micron cartridge. Works like a champ.
