I have the Coralife Super Skimmer, and it does a great job!
The only drawbacks to the CSS are that it takes up more space inside the tank than most other skimmers, and it does take some time to get set up properly, the bubble diffuser box caused me quite a headache for a while. Now that it is broken in, though, it does a beautiful job!
Also, even thought I am only FOWLR
, I still recommend a skimmer. Mine takes out quite a bit of junk and I still have to scrub algae every few weeks...I don't know what it would be like without it!
