I've been hearing that too about the prism skimmers, but mine works FANTASTIC! You just have to find the right setting for it; it takes a little tweaking, but doesn't everything in this hobby. Mine came with the tank I bought, so I decided to give it a try. I have a 125 and a 75. The prism is on my 75 and takes out the most smelly, ugly, and funky stuff in the world!
