I did a bunch of research on this.  From all the experts I read from most of them said a UV sterilizer didn't do much good.  You would have to run all of your water through it to accomplish what you are trying to do and run it slow enough to take affect.  I have used a large nice UV sterilizer for a while.  I didn't notice any difference using it and not.  So I don't use it anymore and my tank water looks great and my sand bed is sparkly clean.  I'm careful about the fish I pick up and dip my corals.  And I have a bunch of algae in my sump, thanks to Mark.]]> Mon, 21 Apr 2014 10:25:07 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563116&title=uv-sterilizer#563116 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563111&title=uv-sterilizer#563111 Author: Mark Peterson

I agree with Dion. Run water through it very slow.
The other thing that I believe UV does is to create either O3 or some other chemical change in the water that somehow inhibits the Ich parasite. I have seen tanks where the Ich was gone within 2 days after using UV.

Crazy talk. It will only kill the items going through it it ran slow enough. The plankton in your water will not be wiped out unless your running it through your return or supply. I run a 47w with a fairly slow flow through it so I know it is doing its job. (most people run it way to fast and it doesn't do its job.)
I'm after controlling water born algae. I wont control it all just cutting down on how much is in there. Same as having 3 filter socks with a bypass flow. If you don't feed the sump nothing will grow ;) ]]> Sun, 20 Apr 2014 22:10:00 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563101&title=uv-sterilizer#563101 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563042&title=uv-sterilizer#563042 Author: Mark Peterson

What problems am I thinking a UV Sterilizer will prevent?
What are the options for achieving the same result?
Am I also thinking of running O3 and what are its advantages/disadvantages?
What animals am I planning to keep? Which animals benefit and which do not?

These are just a few things that would make a difference if I were considering UV.
Personally, I would not run UV for the first 3-6 months because I believe it would hinder the development of the most critical part of reef aquarium health, the biofiltration.
I believe that SPS coral would rather eat the live plankton that a UV Sterilizer would kill.
UV does not kill the bad and leave the good. It kills the same amount of everything. A higher value of UV kills more of everything.

I had a 9watt light on a 400gph cobalt aquatics pump so slow flow which was supposed to kill bacteria which is why I took it off because the bacteria I dose says to remove it. I have a 65 gallon tank.]]> Sat, 19 Apr 2014 19:18:27 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563022&title=uv-sterilizer#563022 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563020&title=uv-sterilizer#563020 Author: Matt

nothing yet. My new tank is still cycling but trying to do the research before I need it. Preventative maintenance is usually easier than dealing with something after it happens.]]> Sat, 19 Apr 2014 19:02:40 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563020&title=uv-sterilizer#563020 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563019&title=uv-sterilizer#563019 Author: Ann_A

Out of curiosity is there anything in particular you are trying to kill with the UV? I personally recommend quarantine and good husbandry to prevent disease and wouldn't use UV as a treatment. I may have gotten rid of the ich with the UV once, but I had it come back many times while running UV. Since pulling all of my fish out and quarantining them for 8 weeks in copper I haven't seen ich in my system.]]> Sat, 19 Apr 2014 18:48:36 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563019&title=uv-sterilizer#563019 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563018&title=uv-sterilizer#563018 Author: Matt

I know I did a lot of research on it but honestly I don't remember most of it. The reason I believe it helped with the ich was that the lifecycle of ich includes a free-swimming stage and I think that's where the UV helped out. I'll see if I can't find some of the information I had in the past regarding intensity of UV and let you know.]]> Sat, 19 Apr 2014 18:36:44 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563016&title=uv-sterilizer#563016 http://www.utahreefs.com/forum/forum_posts.asp?TID=70941&PID=563015&title=uv-sterilizer#563015 Author: Matt

I read that a UV sterilizer doesn't really do much to help get rid of Ich if your fish already have it. Since it is on them and not in the water column. Did you happen to figure out or read how intense it needs to be to kill most of the nastys?
