QT tanks. Seriously, WTF??

[MitchM]

I'll use a QT tank if I'm going to be treating with hyposalinity - that's it.

If I'm buying a new fish (which I haven't for a number of years now), I'll make sure it's been in the LFS tank for a few weeks, and that I know how the LFS tanks are maintained.

IME, popeye has always gone away on it's own and a few water changes probably helped out.
