Hi Deb. I understand that UV isn't needed for treating ick since fish can naturally get rid of it on its own. But are you saying that the Ick stayed on the fish just as long even with your 25W UV running? I would have expected that the more powerful UV would reduce the number of days that the fish will have ick. That would be the benefit.
As for slime algae, yeah, it would have to go through the sterilizer in order to kill it.
So I think its fair to say that its useful for tanks with problems (like mine) and not useful for healthy tanks like yours.
