does UV destroy beneficials?

[DawgOnIt]

I am considering a UV for my natives tank to help minimize the spread of undesireables on my wild catches from fishing trips.

Will a UV Steralizer destroy beneficial bacteria and fluora?

Thx

Yes. IMO, UV is pretty much a waste of time effort and $$$. You will be much better served by using a proper QT procedure.

I use UV on my setups and it helps control ich.
