tank in fallow next to non-infected system

[billsreef]

Assuming theronts were transmitted via aerosol from the DT to the QT, once the medication was removed from the water and they were able to "reach" and reinfect the fish... Is it possible theronts from the "next generation" have already been transmitted via aerosol from the QT back to the DT now, and he needs to restart his 72 day fallow period (after he moves the QT)?

With the two tanks so close, it's a possibility.

I'm also wondering if chemicals such as copper or CP can be transmitted via aerosol from the QT to a DT.

Definitely, though the concentration would be quite small.

Thank you, Bill!
