Is it OK to dose Vodka and run an UV ?

[Casey8]

I want to use an UV for controlling disease in a tank like ich or another kind of bacteria. My tank is free from ich for a long time now, but the dead of my previous fishes are still lingering in my mind and I really don't want it to happen again. I can't set up a quarantine tank, so I prefer to have an UV running instead. Does that mean if I continue to dose Vodka, I will not be able to plug in an UV at anytime ?
