Gonna go with UV, not ozone..
Well I was all ready to use ozone until I read that ideally it should be done through a reactor, so I am now going with a UV.
I got the Emperor Aquatics 50w HO ...i think Bomber recommended it over at the OTHER hated site.
Thinking I am going to plum it off my sump return sort of as a bypass.. so some of the water would flow through straight to the tank, and some would go through the UV and then join up with the rest of the water that bypassed the UV and would go to the tank.
Thinking I should place the ball valve on the bypass side of the T, not on the UV side of it?? That way I control how much water bypasses the UV, and thus actually controlling the flow through the UV.
I read that the flow rate for killing parasites/pathogens is around 550-750gph.
Anyone else care to chyme in here?
I know have brand new ozone reacto, lab grade ORP probe, etc I need to get rid of, so if anyone is lookin to use ozone let me know.

All i can say is... I am tending to agree. UV is simple plug and play whereas Ozone needs a bunch of extra crap including ORP probes, air dryers, etc... If you looking to kill free floating pathogens and algae then UV all the way. Ozone is good for improving skimmer performance from what i hear but i have yet to see it in use.

see that is what I dont get... everyone has this preconception that ozone improves skimmer performance, but when you read the ozone article in reefkeeping, it says completely the opposite, that it hinders its performance.
Anyone care to weigh in on this? Reefkeeping is a pretty reputable source and the author of the article is rather reputable as well....
My idea is to kill pathogens and get my water crystal clear. I may alternate the UV between high flow and low flow...so if I add new fish to the tank, it goes to low flow to kill pathogens... after a few weeks switch to high flow for water clarity.

This is something I've been reading about lately and I havent found a perfect answer yet. What I understand is the ozone competes with the skimmer, not necessarily degrades performance. If you inject ozone into the skimmer, for instance, it reacts with organics in the chamber and breaks them down, and there is simply less for the skimmer to remove because the smaller resulting components don't adhere to the bubbles in the skimmer. What I am curious about then, is what are the organics reduced to? Things that would be better skimmed out? Or perhaps they are broken down into other things that the corals actually benefit from? Who knows?
Good topic.

All I can say is lots of LFS stores run UV, none run OZ.

well that isnt really a fair statement, because most LFS run UV because of their fish holding systems. Apparently UV is better at killing parasites than Ozone is. UV is also a lot safer to use as I dont have to worry about ozone leakage.
I never even got around to setting up the ozone because I found out it is best to run it through a reactor which would have cost me around $600+ for the total set up.
Instead, I got the EA 50w HO UV and hopefully its big enough for my system, we shall see.
Ozone vs UV has always been a hot debate, but I do know most large public aquariums use UV in their systems, so I just figure why not mimic them.

I really like UV, I have an emperor aquatics 40W unit and it does wonders for water clarity. I don't know if it is killing pathogins or not, but it's nice peice of mind anyway. I don't have it installed at the moment, because a sump change out took it's spot, but I have been meaning to re-install it for the last 3 weekends.
UV also breaks down alopathic chemicals used in coral warfare, with how we all like to over-stock our tanks, I think that is another major benifit.
