I did not mean to imply that a UV was not good. I just meant that if you do not run the right amount of water thru it per hour, you also kill the good things is all.

I would just rather kill just the ich and bad parasites by running the proper GPH, then run the wrong GPH and kill everything. As I mentioned before, most people, including myself, believed you just hook up any old pump and away you go.
