Riddle me this.....so I go into the LFS to replace my clowns. I have a sample of my QT water as there is a 7 day guarantee on livestock with a water sample.
The little girl that tests my water says that there's an ammonia reading. No big deal. I can guess why.
I explain to her, that I had an issue with my autofeeder overfeeding my tank and "crashing" it so to speak.
I told her that I replaced about 90% of the water in the tank with water from my tank (that is already cycled). I said I guess I could just dump the water in the QT and replace to whole amount with tank water, and she said, but then your tank would cycle again.
I stated that if I used cycled water, with a sponge from my sump (used for bacterial base), that I would avoid any cycle other than the small spikes of the additions of livestock to the QT. She then got smart with me and said, "Do what you gotta do dude," and walked off.
At this point I was a bit stunned. If I'm entirely missing the basics of the nitrogen cycle here, please correct me.
She said that there's new substrate (no there's not) that will cause the tank to cycle. I calmly stated, "I'm not trying to anger your or make you mad, I'm just telling you if you add cycled water and a mature bacterial base to a glass box, your cycle will be minimal at best."
She didn't like that either. So anyway.....I left. I wasn't trying to talk my way into the guarantee, I was just planning on going home and letting the tank do it's thing for a day or two and try again, while educating someone a bit in the process. Backfire.
Anyway, I just tested my QT for ammonia at home, and it seemed that there is even more ammonia than tested at the LFS. I may have to scrap the QT water, start a new sponge in the sump, clean the qt tank and start over. I don't want to have to go through a whole cycle just to throw some fish in QT.
