I made a big mistake and I'm kicking myself for it now.
Tonight I was doing a WC in my 5.5 gallon planted tank. Tank is also fully cycled and has been for about 1-2 weeks. I had to do some rearranging and replant some plants so I took the filter out and was going to put it in a bucket of water so the cartridge (it's just a foam block) wouldn't dry out and kill my BB. Well, now I'm wishing I'd just left it in the tank. I filled up the bucket I use for water changes and put the filter on, was about to plug it in when I realized I forgot the water conditioner. I know BB can't survive in water that isn't conditioned. It wasn't in this water long, a minute maybe 2 minutes at the most. I yanked it out and added double dose of conditioner and put it back in and started it up. I went on with the water change (with it running in the bucket) and when I went to put it back in the tank, I took some of the filter from my other established tank and wrapped it around this ones foam block. I put the fish in an emergency 1 gallon I have just incase my filter is spewing out ammonia at this point, so he's safe in clean, conditioned water. The 5.5 has a TON of plants, Amazon Swords, Anubias, and Wisteria. So if I go through a mini cycle, they'll be able to help.
Did I totally lose my entire cycle? Am I going to have to start over fresh? I just want to kick myself in the butt right now. I'm usually so careful but I was talking to my mom and just forgot. Ugh. All of this before I go away for 4 days.
