I found this forum 17 years later But discovered the forum first day of when I got 3 new swordtail fish to add to my 9 year old catfish that survived through worse times of uncycled (and unfiltered) tank that had 100% water changes.I did a successful fish-in when I first started. Only because I found this forum on Day 2 before there was any ammonia buildup. I just meant that when telling someone new about cycling with fish, maybe include some of the facts or lead them to the reading material provided here so they will be prepared.
Just saying to "use" platys could lead someone to lose a few fish by mistake.
Only lost one female swordtail during the first week of cycling. She was weakened further by the other female swordie picking on her in addition to the not yet cycled filter, so she stopped eating and, even though I kept her separately and changed water frequently in the bowl 100%, couldn't save her.
Didn't experience bacteria blooms, but the worst part was not having kits until... I didn't even need them anymore 2 months later (of changing water daily in a 23L tank). Then got the 76L tank I have now, moved the filter and stuff to it. And barely back in May I could confirm that the tank has cycled when I had both ammonia and nitrite kits (which both said 0).
Getting out of the muck was pretty hard, especially when I've been sleeping 17 years in it lol...
