I just got all the parts to my filter, API test kit, ammonia, heater and everything is up and running. I think I have the basic idea of how a cycle works. I would like to do a fishless cycle, but I know it takes time adding ammonia everyday. I plan on going out of town for about a week for Thanksgiving and I don't have anyone who can tend to the tank while I'm gone. My question is: Can I start a fishless cycle and take a break without the BB dying off while I'm gone? Could I start it and add shrimp (how many?) to keep it going until I come back? I plan on using some filter media from my goldfish stocktank from outside (unless that's a bad idea) to try to get it going. My FIL thinks I should just use some hardy fish (then flush them when I'm done), but I don't want to do that. What do you think? Thanks!
