almost got it all :)

There is occassional cause to supplement the use of Zeovit with sterilization methods such as UV or Ozone, one of them being in the advent of a bacterial bloom from overdose of Start2...

By far and large though, it's completely unnecessary once you hit phase 2/3.

Yes, rather than a university staff room (with it's plethora of 'professors' and 'experts').

I'm going to side with those that feel that the bacteria don't proliferate in the water column. If your tank is overstocked or has a high bioload, UV is probably best for the health of your fish... otherwise shouldn't really be needed. And UV makes your water nice and clear (when used with a skimmer).

The purpose of a UV sterilizer is to kill Bacteria.

Those are the basic functions. they simple can not exist together in the same system.

The amount of bacteria in the water column in negligible compared to the bacteria that colonizes every other surface in the aquarium (think live rock). Hence bacteria on the rock will never be killed by the UV sterilizer.

It's entirely possible and more likely probable that the bacteria that gets added gets a chance (in the hour or so of no UV) to settle on a hard surface and is proliferating and active there.
