2 uv or not 2 uv that is the question

I was about to post the same question.... interested in hearing what others have to say.

 

You could plumb it so it's easy to put in and take out. If you add new fish or have any problems you could hook it up for a little while, then take it off when it's not necessary...

 

I am with adam on this on. I do have a UV but don't run it all the time. I turn in on if I notice some ich starting to develope on my fish, mostly my tangs. After a while you really don't need it, but would be a piece of equipment you would want to have around just in case of an out break.

 

Welll, in a perfect world we would not have any trouble with parasites because we all QT before adding livestock. So in this case you don't need it. Before I added one I had read that it makes your water clearer because of certain micro algae's it kills in the water column. When I tried one I found this to be true although I would not say why. I think them killing pods is a myth but I would not swear to that. I took mine out because I didn't want another $50 bulb to replace every year.
So my conclusion is: if you QT you don't need it for parasites. It isn't extremey effective here anyway because many of the critters never get loose in the water column to go through the thing. I think we all know that Petco is a definate source of Ich and they run UV on everything. But if you want a little clearer water then maybe go for it.

 

Save your money, go buy some frags instead.
