I’ve set up, taken down, and re set up a qt a bunch of times. Never used nitrifying bacteria or cycled it in any way. I’ve used water from DT, pvc bows to hide in, heater, thermometer, HOB filter, air stone. Bare bottom. Simple and clean.
It really depends 0n the use of QT. If you're trying to combat a parasite using water from DT will keep contaminating the water. It also depends on how many fish are being housed in the QT tank. Ammonia will quickly rise if there isn't enough beneficial nitrifying bacteria.
The number of fish spiking ammonia is a fair point. I’ve put up to 3 (all about 3 inches) in a 20g qt to treat w copper w just a HOB filter, air stone, heater and pvc elbows. No water change for the 2 weeks of treatment. No live rock. No water conditioner. Bare bottom. No ammonia spike. Maybe I got lucky.
You know what I never understood? Why tank water was a bad idea when fighting parasites. If the fish have them already, and your about to kill them w meds, does it really make much of a difference? Guess it would increase the number of parasites for a short while so that can’t be good. But it also ensures that 100% of the parameters are exactly the same. I dunno. Seems more like an issue to use contaminated DT water to qt a new fish but then, if DT is contaminated, it’s probably not the best time to be getting new fish anyway
That’s just my 2 ce Rd.

I agree using DT water during the initial setup is the way to go for the water chemistry and bacteria, but water changes should be conducted with a fresh batches. Since there is 10 fish in the DT ammonia will quickly rise in this scenario. Water changes daily will be important or based on the ammonia badge reading.
Will do!Keep us posted please and good luck!
