I was starting to do a water change to my tank at work on Friday when we had some altercation at work that I had to go handle. After a half hour of taking care of this problem and wanting to throw this kid through a wall, I forgot about my water change. I unplugged everything, so the filter has been off since friday afternoon. It's now sunday morning. There are a dozen guppies in the tank. My concern is that I may have killed the beneficial bacteria that I was building up and I dont want to start all over. Is there a chance that it is all still ready to go after I swap this water out tomorrow?
