I disagree.

UV has pros and cons.
The water column gets pristine because the UV kills all the plankton in it.
High power UV and max efficiency with slow flow is certain to leave nothing alive coming out of it.
It's use on reef health has been debated for decades and I have nothing to add to that.

I'm glad it seems to have worked for you but what happens when you turn the UV off for a week or two?
