IME was the best 100$ I spent... Had an ich break out in my tank about one month ago, I did not realize that at first till my gang got it. I don't have a quarantine tank, so after talking with the LFS I got convinced to buy one, so I got the twister by coralia....
In about 4 days the ich on the tang disappear and now looks so healty...
There is a chart about the uv sterilizer I got, low flow to kill parasite,like ich, medium flow for algae grow and high flow to kill bacteria....
That just my experience, I had a 30 g for over 2 and 1/2 year without running a uv, after I saw what happened to my tang I give to the uv a must have....
