Tap water for a QT container.

[Mike7744]

2 of my 5 fish have ICK , I'm going to quarantine all of my fish and treat with copper. My problem is that my fish are big, 3+4 inches. I don't have a tank big enough for all. So I'm going yo use Rubbermaid 32 gal trash barrel ! Would this be big enough? They are in a 125 gal display tank.
On the water issue. My tap is 50 TDS . Could I use tap water in the QT tank?
I won't have the option to use my RODI system for the water in the QT. I need to put the barrel I'm my heated shed and keep the trash barrel there for the total time of treatment.
Thanks

It should be just fine to use tap. Word of warning, if one fish has ich in the tank, then every fish has it.
