I have a 180 gallon reef tank. It has been set up for over a year. I have been using a Coral Life 220 Protein Skimmer. For the last five months, the skimmer has not been performing very well. I am now on the search for a replacement skimmer. I was looking at an AquaC EV 180, EuroReef RC 180, and a Precision Marine Bullet-2. I had purchased a EuroReef RC 135 model and ran it on my tank for about a week. I was not satisfied with it because the motor was malfunctioning. I called an spoke with a EuroReef representative and they recommended, of course, that I buy the RC 180 - a larger model. I was wondering if anybody has any experience with any of these skimmers, or if anyone would recommend a high quality efficient skimmer for my aquarium.
