UV Sterilizers

(2) Question: Will a UV Sterilizer kill off my beneficial copepod & other crustaceans colonies in my reef tank?

Although not as common a question as the previous question, it still crops up from time to time and I have much harder time understanding why otherwise quite advanced reef keeper fall for what amounts to a UV Sterilizer myth.
As well, my controlled studies admittedly did not include exact counts of copepods with different levels of UV Sterilization or none at all, it did show that copepod colonies when properly established never diminished with UV Sterilizer use in reef tanks.

We run a UV on our main display, which is only about 1/2 powered for the size of the tank.

Really? Why?
And at what flow rate are you running it? To kill algae? or to kill parasites? (in other words what is your goal with this?)

If I can remember correctly; I believe UV light causes Ozone to be produced... That might be what Allan meant...

Alan has an Ozone Generator and is using a UV Sterilizer. I don't think you need to use the UV when you have an Ozone Generator.

No, an electrical charge is necessary to produce o3, similar to an electrical storm and the scent that accompany it.

I do run both, the uv was first and I wasn't impressed so I pestered Ross till he sold me his :-)

I run a 39 watt turbo twist but the flow, I beleive, is fast enough that I don't get a significant kill stats. The o3 is very apparent when it runs ( faulty timer sometimes zero out and I don't realize till the water starts looking cloudy), couldn't be happier.

I have a UV on my main dislplay tank. I also have my fuge inside of my sump. I just plumbed my UV around my fuge so it would not harm my pod population. I have had the setup for almost a year now and I have a happy and healthy mandarin.
