Uv sterilizer

[sergifed91]

I got a Corallife 12x 36watt UV Sterilzer looking to get a second one. What size do I need to go with. I'm wanting to control algea and parasites. It's a dual overflow reef tank. 125 gallon and. 55 gallon sump.

It sounds like the ideal setup would be to just run one on each of your returns, so probably a second one of the same. I wasn't able to get a clear idea of how much x flow you need with y radiation to yield z exposure, though. The manual says 11,400 µw/cm2 - but that seems really low compared to the AquaUV that I run that generates 90,000 µw/cm2.
