Can you use DT water for quarantine/treatment tank?

[CyberGuy]

I plan to set up a 10 gallon tank to to treat possible fungus/bacteria infection on half of the mouth of my wrasse. Can I just use 10 gallon of DT water and put it in the 10 gallon treatment tank since the fish has been used to the DT water.
Or should I just use 10 gallon of fresh mixed salt water?

Yup dt water is fine.

I would almost recommend it. The parameters will match a lot closer vs a new batch of sw

Third opinions above!!

Actually preferable for all of the above reasons...

Agreed

Thanks. I just drained 10 gallon from my DT and used it in my treatment tank.

There's two schools of thought on this:

1. Use fresh SW, fully mixed, for your QT, as you will ensure you don't expose your fish to any pathogen that might already be in your DT.
2. Use older DT water, as it is exactly representative of the parameters the fish will see someday, and you do get (some) free-floating bacteria that might be beneficial.

But the first point is rather moot if the fish has already been in your DT.

I do this all the time. Originally it started as a way to more conveniently acclimate new fish from QT to the display, since I already had buckets of old water change water in front of me, it made sense to just use it directly in the QT.

Cant say if it's any better than fresh new water but never saw harm.
