I've had a Corallife super skimmer 125 running constantly for over 6 years. Ive never had any issues with it. It's one of the cheaper skimmers On the market and I'm sure there are better, but for the money( think I got it for like 130 on sale) it's performed great!
I'm now looking for another skimmer, as this one is under-sized for my 180g reef, and am considering the Corallife 220 because of the performance and longevity of the 125.
I would strongly advise not to get a Coralife SuperSkimmer. They aren't worth the money. You would be better off saving a little more and getting a good skimmer. I had 1 and they are only good if you have nothing to compare it with. Currently I'm running an Octopus Extreme XS 200 on my 125 and it's a great skimmer.
