I've got a 29g that I just set up in our living room, and I've cyled tanks before, but I don't want to wait so long! I've got a 55 and a 20 in my bedroom that are both fully established, and I'm planning on taking an entire hang on back filter, media and all, from the 55 and running it on the 29 for a few days. How should I go about this? I know the bacteria will need ammonia, so how long should I let the filter run before I add a few hardy fish? And is there anything else I forgot that I should do during this process? Any information is appreciated!
