UV Sterilizer

[Megalodon]

I know the UV kills everything, I just wondered if anyone had problems with their plankton dieing. I understand it can still be consumed by inverts if the plankton is dead and still fresh. Don't we kill all our plankton with pumps or mechanical filters (some of us) anyway? Or add what I assume is dead plankton in those bottled commercial remedies?

I'm not debating... I really don't know. Thanks.
