Bigger is better when it comes to a protein skimmer, right? Not necessarily. Using a high capacity protein skimmer on a smaller tank can be problematic. Why? Well, using an oversized skimmer will result in an inconsistent performance. Let me explain. To perform optimally a skimmer should be working all the time.
