UV works best with a longer exposure time. i have a 530 gph canister with a built in UV. To be effective, the flow rate would need to be closer to 100 gph. IMO the UV built in to a canister is a waste.
I have had terrific success with neutralizing algae with UV. I've run UV on tanks for pathogen control and not noticed any difference as far as incidents of sickness or whatnot when compared to the tanks without UV. It's more anecdotal evidence than scientific, as there were LOTS of differences between tanks.
