Water Filtration for the Lower Mainland

[BCOrchidGuy]

UV filtering is used in biologically dirty water OR and probably better in your reef tank to keep the nasties down. Unfortuneatley it also kills benneficial bacteria etc.

I am giving some thought to a UV filter run out of my sump, just to keep the parasites etc down. I figure if I just run it from the sump back into the sump it won't be a big deal as far as killing of the goodies.
